[SDL] Problems with glXGetSwapIntervalMESA on FC6

[Kostas Kostiadis]

Hello all,

I've recently installed FC6 and apps that were working on FC5 now give me
this:

"Failed loading glXGetSwapIntervalMESA: /usr/lib/nvidia/libGL.so.1:
undefined symbol: glXGetSwapIntervalMESA"

I'm pretty sure there is a trivial solution to this (i.e. install a missing
package) but I'm not sure what it is...

Has anyone encountered anything along those lines?

Cheers,
K.
