You can use environment modules: http://www-theor.ch.cam.ac.uk/IT/software/modules.html Install separate instances of the software under /opt and play with the environment variables like PATH, LD_LIBRARY_PATH etc. I went through the same process back during the Redhat RH2.1 to RH3 transisiton. glibc3.3 where not compatible with glibc3.2 so we used modules to manage to run expensive HPC software not yet released/compiled for RH3. -- MortenB -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
