Also, make sure that your QT has the threading supported if your OpenGL is multi-threaded. When you compile your own QT, check for a small notice (that could be easily overlooked) after typing \"./configure\". It appears after the command and before the copyright notice. I needed, type \"./configure -thread\"; QT normally compiles without threads.
Ted,
I built 3.3-2 with -thread and used both the FC2 and dynamic version of Skype for Linux
and still get choppy sound. So, in my case, the problem lay elsewhere.
(Same hardware, with a different boot disk, run Skype for SuSe just fine!)
