I just posted an updated version of a Dependencies install script, for
fedora 10 and svn, on the mythtv wiki under Howto -> Dependencies
(Building from Source). It makes building a new install rather easy.
It probably works for .21 and .21-fixes too, as it just uses yum to
install packages for myth (and mytharchive, mythmusic and mythvideo).
There are 123 listed packages including kernel-headers and such which
will pull in and install the OpenGL glue which might be missing for your
(new) kernel. (There 2 packages which I think have been subsumed into
something else as I cannot find them in any repo.)
I don't know that it will help your problem but it might.
Two questions however:
Did you check that /usr/lib/qt4/bin is installed *before*
/usr/lib/qt3-3/bin in the PATH of your mythfrontend user?
And do you have Composite Extensions disabled in xorg.conf. I think the
latter 'on' is a killer for OpenGL.
Please let me know if anything I say offends you.
I may wish to offend you again in the future.
