so in entropy we have

octave v3.6.0 and in portage

octave v3.6.1. because octave ebuild is in the main gentoo portage tree this means that very soon will be in entropy database ...

but still here is different time ecarts ... if you really want to have last version packages you should use sabayon-limbo repository ... this is for development and test of latest gentoo packages scheduled for inclusion in sabayon entropy database

if a new package is still with with no bug reports and no crash at sabayon build farm and test machines will end in main sabayon repository in no more that one week ...

for ebuilds which is not in main gentoo portage tree but in some overlays i am not sure but i think that is not updated so often like is from gentoo portage

if you cant wait a week for octave 3.6.1 always is a last solution, install directly from portage

it is an safe operation if you do not alter too many useflags and if emerge do not want to rebuild too many libs

for example, in my case, because octave 3.6.0 is not instaled:

- Code: Select all
`emerge --pretend sci-mathematics/octave`

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

THIS IS NOT safe! too many unnecessary libs rebuilds using portage

so,

NOW IS SAFE to install latest portage octave in sabayon linux using portage & gentoo way because as you can see is only main octave software upgraded all other needed libs is installed from entropy database

if octave ebuild fail to compile is only his guilt and until in sabayon-limbo repository and gentoo portage tree this problem is not solved entropy octave v3.6.1 binary package will not slip to stable sabayon repository because, as you quess, will fail to build in sabayon-limbo first ...

this is why sabayon linux is not just another binary linux distro ... is gentoo but gentoo on steroids
