In Debian package list I didn't found any openGL... library nor
libMesaGL... but only xlibmesa...

I found in /usr/X11R6/lib the package libGL.so.* I renamed it and
created a link named libGL.so.1 to libOSMesa.so.3.3, because
there is no library called libMesaGL.so, but this don't works.

I search for libMesaGL in Debian site within the packages
page with no results, and a general search in the web point me
only to RPM packages;
Searching in Debian packages page again, only with "mesa" word
I found xlibmesa3 package that is the one I installed and it
supply the lib libGL.so.1 and I think is the one I found
in /usr/X11R6/lib dir.

So I thougt that in this Debian System I'm using (3.0 woody)
libMesaGL was called libGL.so.1, but at this point it comes
out the strange message that requires GLX extension and this
indicates that I'm using openGL...

I think I need some help! :)

Thanks, Michele.
