The use of Portage and Entropy in the same Sabayon, is not so easy, although may be carry.But in your case, now the new GLIBC, is now in the database of Entropy, "normal" Portage and in the Sabayon overlay also...
Instalable with equo or sulfur.
Keep using entropy (equo) in Sabayon and ready, study, wow to use portage.
the command that you tried:
- Code: Select all
layman -s glibc
is erroneous, since GLIBC is not an Gentoo Overlay.
