[Cooker] Mesa ????

[allxsan]

I have a big trouble with Mesa-3.0.99-5mdk.

I don't understand!!! this file contains some strange thing:
libGL, libGLU, libglut....

I'm really surprised when some software reports that cannot find shared lib
libMesaGL.so.3 ( etc. ). 
Downloaded and compiled the same version but in SRPMS format and....
surprise !!!
My new generated RPM contains the right files libMesaGL, LibMesaGLU...

Whats happen?

Many thanks
Alessandro
