Rubber Band Gun #6 and Pro/Engineer Wildfire

Posted in AppCove, Linux, reSearch, tagged EPEL, Linux, RPM, YUM on February 8, 2009 | 1 Comment »

On a brand-spanking-new RHEL 5 box, I installed the YUM repository for EPEL, and quite immediately had access to tons of extra packages. Erlang is there. [...]
