While doing an update of libvorbis the ./configure phase fails when checking whether gcc produces valid executables. When running the same test manually the following happened. minimon libvorbis-1.0 # gcc -Dsimd-3dn conftest.c conftest.c:0: malformed option `-D simd-3dn' I tracked the macro entry down to a line in the ebuild. # if [ `use x86` ] ; then # use sse && epatch ${FILESDIR}/${PN}-simd.patch # use 3dnow && append-flags -Dsimd-3dn # fi By disabling the lines related to this macro entry, the ebuild works. I could then update libvorbis.

The reason it fails is because you have 3dnow in your use flags, and since a Celeron does not support 3dnow instructions, the test fails. Remove 3dnow from your use flags and it should configure just fine.
Yep, that'd be the cause. Thank-you.
wrong CFLAGS
