What do you get from this command?

    ldd blib/arch/auto/Glib/Glib.so | grep libgtk

Does this print the /net/bmachine/x/rich/usr/local/lib path, or does  
it print /usr/lib?


When linking, the Makefiles supply the correct -L$path line and the  
linker can find the correct libraries.  HOWEVER, if that directory is  
not in your system's normal runtime linker search path, the system  
will not look there at runtime for the library!

If the command above prints out /usr/lib instead of /net/bmachine/x/ 
rich/usr/local/lib, then this is what's happening.  Try doing this:

    export LD_LIBRARY_PATH=/net/bmachine/x/rich/usr/local/lib: 
$LD_LIBRARY_PATH

and then run the build command again.  If that fixes the problem, you  
have a few options:

   1.  Add /net/bmachine/x/rich/usr/local/lib to /etc/ld.so.conf   
(not recommended, as you must be root)
   2.  Add /net/bmachine/x/rich/usr/local/lib to LD_LIBRARY_PATH in  
your shell's login setup
   3.  For scripts that use Gtk2, use a little wrapper script that  
sets up the environment appropriately.

After a few years of messing up my systems, i heartily recommend  
option 3.  You'll probably need this anyway for setting PERL5LIB to  
point perl to a nonstandard install location for Gtk2.
