Re: [gentoo-user] Updated gentoo systems and fresh installs

[Trenton Adams]

Thanks everyone.

Just so you'll all have an extra tidbit of knowledge.  A co-worker
mentioned one other thing that could be a problem, that no one else
mentioned.  If you have not yet upgraded GCC on an old version, then
use an up-to-date installation with a newer GCC, you will have binary
incompatibilities with your package build system.
