Hi everyone,

I'm trying to compile the Kdenlive trunk after upgrading Ubuntu to version
11.04, and I'm getting the following linking errors :

It looks like a problem with the QtOpenGL library, I tried removing and
reinstalling the library, with no more success.

Does anyone have an idea of how to wolve this issue ?

Thanks,
Hugh
