If I have 4 or 5 versions of say pgi or intel compilers that I need to make available on a compile server, and each version installs into it's own directory tree, such as /opt/PGI/6.7.8 & /opt/PGI/6.7.9 , etc... then can yum do this? Will it complain and/or try to upgrade? Would I use installonly? How do I do this? There would be no conflict per se, and I've been doing this with rpm, and wish to move to yum.
