Hi Trond,

the problem with precompiled binaries using shared libraries is that the
path to the library and its name/version are set at compile time. Please
read the README.mesa31 file i wrote for mesa3.x. 

First check if you have installed the libraries: 'locate libMesaGLU.so.'
The mesa3.1/3.2 libraries are named libGLU.so.1 if i remember correct. 

If the library is not found, you should first install mesa3.x (from
source or from rpm) and then compile grass.

If the library is found in /usr/local/lib you must either add
/usr/local/lib to your library search path (done in the file
/etc/ld.so.conf if i remember correct, see man ldconfig for details) or
you must issue 'export LD_LIBRARY_PATH=/usr/local/lib' befor you start

If the library is in /lib or /usr/lib or has another name you are out of
luck and must recompile grass.

Hint for the people who compile the grass5 binaries: either state that
it is compiled against libMesaGLU.so.3 (mesa3.0) or install mesa3.2 on
the machine and recompile the binary. I don't know which mesa version
other distributions than Red Hat have installed. It seems to me that Red
Hat at the moment is a bit too far ahead in implementing new libraries
(glibc2.1 etc).
