[G12] Next problem -- sample gsim script

[Craig Bookwalter]

  Hi Carlos,
   It doesn't work on the 64-bit machines because they don't have the 
same library versions between CentOS 5.3 and Fedora 8. It's easy to fix 
on a case-by-case basis but a general fix is more difficult. If you're 
trying to adapt the sample script to run your personal MC, I just 
softlink the missing libraries into $HOME/lib or somewhere similar, and 
then add $HOME/lib to my LD_LIBRARY_PATH. For example, gsim_bat as built 
in the STABLE 32-bit build needs libXm.so.2, but CentOS 5.3 has 
libXm.so.4 -- so I would do:

ln -s /usr/lib/libXm.so.4 $HOME/lib/libXm.so.2
export LD_LIBRARY_PATH=$HOME/lib:$LD_LIBRARY_PATH

Techinically this is a bad practice because the version numbers are 
there to make sure you use the same shared libraries a program was 
compiled against, but for standard stuff like Motif it shouldn't be a 
problem.
