(In reply to comment #0) > CPPFLAGS="-O2 -march=athlon-xp -mfpmath=sse -pipe -fexceptions" dont use compiler flags in CPPFLAGS, this will fix you problem.
* checks make.conf * blinks * wonders how, and when, CPPFLAGS got changed from "-fexceptions" to "${CFLAGS} -fexceptions"
I confirm that the problem here is that moc chokes on -fexceptions in CPPFLAGS. The reason I was using that, however, is that dev-libs/ppl requires dev-libs/gmp be built using CPPFLAGS=-fexceptions. See https://bugs.gentoo.org/show_bug.cgi?id=329615 for proposed fix to dev-libs/gmp and dev-libs/ppl.
