There is a way to downgrade for the brave. quickpkg glibc move the 2.11.? version ebuild you want to your local overlay. Edit it and find the check that disallows downgrades. Comment it out. Mask glibc2.12 update glibc At this point it's probably very wise to rebuild at least system, then revdep- rebuild. Note that rebuilding system might fail in which case you are really up the creek. Feel free to rip to pieces the dev that committed this version. It could not possibly have undergone decent testing -- alan dot mckinnon at gmail dot com
