=====================================

Lots of  "undefined reference" messages the cause of the problem?
I also thought that XvMC support was mainly for nvidia cards, I don't
have a nvidia card in this machine and its not in my use variables, so
can I safely disable XvMC support and if so how?:

=====================================

bash-2.05b# ACCEPT_KEYWORDS=~x86 emerge -pv =mythtv-cvs

These are the packages that I would merge, in order:
