Installing KDE 4.5.1: Advice please [Solved]

[Fitzcarraldo]

I would like to install KDE 4.5.1 via Portage, so decided to check for any blockers:

Code: Select all

# emerge -1vp kde-meta

These are the packages that would be merged, in order:

Calculating dependencies... done!

emerge: there are no ebuilds built with USE flags to satisfy ">=kde-base/kdepimlibs-4.5.1[aqua=,-kdeprefix,semantic-desktop]".
!!! One of the following packages is required to complete your request:
- kde-base/kdepimlibs-4.5.1 (Change USE: +semantic-desktop)
(dependency required by "kde-base/kdeplasma-addons-4.5.1" [ebuild])
(dependency required by "kde-base/kde-meta-4.5.1" [ebuild])
(dependency required by "kde-meta" [argument])
#

OK, seems I need to enable the semantic-desktop USE flag to get kdepimlibs-4.5.1 to build:

Code: Select all

# USE="semantic-desktop" emerge -1vp kde-meta

These are the packages that would be merged, in order:

Calculating dependencies... done!

!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:

dev-python/sip:0

  (dev-python/sip-4.10, installed) pulled in by
    (no parents that aren't satisfied by other packages in this slot)

  (dev-python/sip-4.11.1, ebuild scheduled for merge) pulled in by
    >=dev-python/sip-4.11 required by (dev-python/PyQt4-4.7.6, ebuild scheduled for merge)
    (and 1 more with the same problem)

dev-python/PyQt4:0

  (dev-python/PyQt4-4.7.3, installed) pulled in by
    (no parents that aren't satisfied by other packages in this slot)

  (dev-python/PyQt4-4.7.6, ebuild scheduled for merge) pulled in by
    >dev-python/PyQt4-4.7.3 required by (kde-base/pykde4-4.5.1-r1, ebuild scheduled for merge)


It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously.  If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously. You may want to try a larger value of
the --backtrack option, such as --backtrack=30, in order to see if
that will solve this conflict automatically.

For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.


emerge: there are no ebuilds to satisfy "=dev-lang/python-3.2*".
(dependency required by "net-zope/zope-fixers-1.0" [ebuild])
(dependency required by "net-zope/zope-interface-3.6.1" [ebuild])
(dependency required by "dev-python/twisted-10.1.0" [ebuild])
(dependency required by "kde-base/kajongg-4.5.1" [ebuild])
(dependency required by "kde-base/kdegames-meta-4.5.1" [ebuild])
(dependency required by "kde-base/kde-meta-4.5.1" [ebuild])
(dependency required by "kde-meta" [argument])
#

OK, so it looks like I've got to upgrade dev-python/sip from 4.10 to 4.11.1. Fair enough. But the error message "there are no ebuilds to satisfy "=dev-lang/python-3.2*" has got me perplexed, as I have today done an emerge --sync and there is no python-3.2* in it:

Advice please, anyone?

[joost]

Have you also tried putting a mask for python version greater then the one you currently have?
You should really not want python 3

I have this in my package.mask:

Code: Select all

#Joost Ruis: Needed by masked python:3.1
dev-python/beautifulsoup:3.1
>=net-zope/zope-interface-3.6.1

edit:

If you check out the zope-interface-3.6.1 ebuild:

Code: Select all

# net-zope/zope-fixers is required for building with Python 3.
DEPEND="dev-python/setuptools
   net-zope/zope-fixers"

Reason I put the mask there in my package.mask

[Fitzcarraldo]

Thanks for the quick response.

I didn't have any zope packages installed:

Code: Select all

# eix -I zope
No matches found.
#

I've just now added the following to /etc/portage/package.mask:

Code: Select all

 Mask to enable installation of KDE 4.5.1
>=dev-lang/python-2.7

#Joost Ruis: Needed by masked python:3.1
dev-python/beautifulsoup:3.1
>=net-zope/zope-interface-3.6.1

and an 'emerge -1pv kde-meta' told me that gwenview-4.4.4-r1, kde-meta-4.4.4, kdegraphics-meta-4.4.4, kdebase-meta-4.4.4 and konqueror-4.4.4 were blockers, so I un-merged them and have kicked off an 'emerge -1v kde-meta', which reported a total of 266 packages needed merging. I'm off to bed and have my fingers crossed. If it runs to completion I'll see if genlop will tell how long my Core i7 took to build them all.

[Fitzcarraldo]

All done. According to genlop, it took circa 3 hours 43 minutes to merge the 266 packages. Not bad. Thanks again.
