I don't believe your pentium 4 supports 3dnow!

[Comment 2 konsti 2003-09-30 13:41:47 UTC]

yes, but as I told above even
env USE="3dnow -sse" emerge libvorbis
made libvorbis full functional.
The 3dnow use flag was in my /etc/make.conf since the first time I installed
gentoo (I had an Athlon then). Since this year I have an P4 and libvorbis
broke one or two weeks ago...
