I've started seeing this line after failed emerges:
checking for C compiler default output file name... configure: error: C compiler cannot create executables Checking gcc-config returns this: carter sys-devel # gcc-config -l * gcc-config: Active gcc profile is invalid! [1] i686-pc-linux-gnu-4.3.4 How can I get gcc back? Here's some other information on the system: carter ~ # emerge --info !!! No gcc found. You probably need to 'source /etc/profile' !!! to update the environment of this terminal and possibly !!! other terminals also.
