portage-126.96.36.199 failed to upgrade without installing dev-util/colorgcc first.
portage seems to be looking for /usr/lib/colorgcc/bin, and fails to install if it does not exist.
Steps to Reproduce:
1. emerge -uD portage
install failed due to missing /usr/lib/colorgcc/bin
either for this check to pass, regardless, or for portage to pull in dev-util/colorgcc as a dep first.
i soloved this by simply emerging colorgcc first, then installing portage.
This is in no way reproducible. Maybe check your PATH/aliases/environment.
Maybe it's something in /etc/portage/bashrc?
There is no reference to colorgcc in the portage sources.
bah, very sorry for that.
