[mythtv-users] mythfrontend segfault on gentoo - solved

THANK YOU ... I've spent the better part of a week trying to figure out what
I did to break mythfrontend / mythtv-setup ... I re-emerged every single X
library in multiple ways, trying to figure out what the recent updates (two
weeks ago I did a full world update) did. I don't know why I didn't even
think to check the opengl selection.

To be more precise, my eselect profile for opengl was still set as it should
(I only have the xorg-X11 opengl, as this system is pretty much
backend-only); however, some of the symbolic links that the eselect setup
creates were broken, so I re-ran eselect, checked that the symbolic links
were now re-created, and voila.

Again, my gratitude is yours for as long as my Myth system goes without
something else breaking ... That's why we do it, right?
