No OpenGL in MythTV?

Hello,

I've been building MythTV from source for years (mainly so I could hack
on it, and occasionally submit patches), but I've decided to save myself
some trouble and start using the packaged builds.

I might be doing something wrong, but it would appear that MythTV was
built without OpenGL support. There's no OpenGL listed in the theme
painter options (only Auto and Qt), and I can't create any playback
profiles with OpenGL either. Assuming I'm not doing something wrong,
was this intentional? Or an oversight?

Thanks!
