I think bug #146448 [1] is the most relevant bug (which you should be able to 
find on your own). Unfortunately it provides no solutions. This package 
simply isn't prepared for gcc-4.x yet.

Apologize my ignorance... Why do you need this package anyway? No package 
currently in the tree depend on sci-libs/lapack...

Hmm.... actually this seems to work for me:

# echo -e '#!/bin/sh\ngfortran -ff2c' > /usr/bin/g77 && chmod +x /usr/bin/g77
# emerge -va sci-libs/lapack
# rm /usr/bin/g77

I strongly suggest that you remove it when you're done since this isn't the 
supported solution. At the very least mention it if you ever file a bug where 
it might have an impact...
