emerge mythtv fails with error of: X11/extensions/XvMClib.h: No such file or directory on a system running xorg 7 and without libXvMC.

no it's not. It's in the dependancy. Read the ebuild. You still have your old xorg stuff installed or something funky that is providing virtual/x11 which is going to break dependancies.
You have like this in your system... http://gentoo-wiki.com/HOWTO_Modular_Xorg#.27emerge_-u_world.27_wants_to_install_xorg-x11_6.x_or_virtual.2Fx11 get rid of it.
Thanks, that solved the problem.
