Libdv
gcc-4.1.1 seems to make troubles with libdv-0.10x. When applying the following patch it will compile without problems http://sources.gentoo.org/viewcvs.py/*checkout*/gentoo-x86/media-libs/libdv/files/libdv-0.103-mmx.patch
another solution is to issue: ./configure --prefix=/usr --disable-asm
The above patch is also upstream here:
http://libdv.cvs.sourceforge.net/libdv/libdv/libdv/mmx.h?r1=1.3&r2=1.4&view=patch
