I think you're using old instructions. We were passing
--datadir=$XORG_PREFIX/lib because the early autotools for 7.0 were
kind of messed up and this was an easy workaround to get things to Do
the Right Thing. But, as you found out (and a lot of other people
reported), this is wrong. Especially for the autoconf macros.

Hmm, when I was going through the files for the drivers last night, I
saw that xf86-video-via-0.2.2 installs a libviaXvMC and libXvMCPro. Do
you get those?

I read something about this a while back. As I understand it, there
are 3 different drivers, all with different feature sets because no
one can get along.
