[Mesa-users] Building Alternate Mesa

[Dan Allen]

Hi,

I had set these variables when the result was as originally described.

For information, I used --prefix=/opt/mesa during configure and then 
sudo make install after compilation. I then used export 
LIBGL_DRIVERS_PATH=/opt/mesa/lib/dri and export 
LD_LIBRARY_PATH=/opt/mesa/lib.
