I recently was in a similar situation, but was trying to just
completely eliminate the fact that I ever tainted my kernel with
anything from nvidia. What a problem that caused! I completely
removed nvidia anything, removed xorg, recompiled and reinstalled
xorg, but still had a few traces of nvidia crap around :(
I eventually just grepped my system for anything looking suspicous,
removed it, reinstalled quite a bit of things to make sure they were
no longer being attached to anything nvidia, and finally was able to
get a truly nvidia-free system working. About 20 minutes later, I
reinstalled the nvidia drivers :D
Anyway, back to your question. I'd personally just remove (emerge -C
nvidia-kernel nvidia-glx) the emerged nvidia drivers, and then using
the nvidia installer, remove the old (new actually) one as well.
Then, re-emerge the older version (emerge nvidia-kernel nvidia-glx)
and then re-install/emerge mythtv to make sure it's all setup and
Directly answering your question:
I'm running SVN MythTV, gentoo on an AMD XP 2500, and here's the info you want:
ls -l /usr/lib/libXvMC.so
lrwxrwxrwx 1 root root 14 Jan 12 19:21 /usr/lib/libXvMC.so -> libXvMC.so.1.0
mythslave ~ # ls -l /usr/lib/libXvMC.so.1
lrwxrwxrwx 1 root root 14 Jan 12 22:28 /usr/lib/libXvMC.so.1 -> libXvMC.so.1.0
No longer have an XvMCConfig, removed after I did all the things
ldd /usr/bin/mythfrontend | grep XvMC
libXvMC.so.1 => /usr/lib/libXvMC.so.1 (0xb6a7a000)
