I just recently migrated to Linux and I'm still figuring out some of the basics. Please go easy on me. I'm running yum 2.6.1 on Fedora Core 5 I have gcc 4.1 installed on my machine and one of my software packages requires gcc 3.5. How do I get yum to download that specific version? Then how do I get that particular software to use that particular version of gcc? I read through the faq http://wiki.linux.duke.edu/Yum and the man page and I see a command for getting the version of yum but not one for getting a version of a certain program. Thanks for any and all help. Joelle
