Please submit a bug report on that one... it might also be related to
the following though:

Check that you don't have more than one gcc version installed. This
seems to come up a lot, and the reason usually turns out to be that more
than one gcc is installed. If it still craps out, please report in
bugzilla.

Please check out package.mask, there are several gcc3.1 patches in there
which need to be tested before being unmasked.

Also, use a portage compiled with gcc 3.0.4 or 2.95.3... that works
around a known problem with sandbox/gcc3.1.

Also, if you get unresolved symbol issues with fam-oss, try a "make
mrproper" on your /sur/src/linux after backing up your .config. Then run
"make dep clean" after restoring your .config.

Keep the gcc3.1 issues coming :)
