Build log

Doing the "emerge portage" command resulted in a failure of dev-lang/python-2.7.3-r3:2.7 to compile. I was told to report this on the forums.

Portage 2.1.11.31 (default/linux/powerpc/ppc32/13.0, gcc-4.5.4, glibc-2.15-r3, 3.8.13-gentoo-iMac-G3-Server ppc)

Solution: Do not put -pthreads in your CFLAGS.
