Just my luck, None of my CentOS systems or my Fedora systems can #yum groupinstall "Development Tools" "Development Libraries"? Both are having dep issues? Is that a coincidence, or what's going on? The CentOS boxes all complain: --> Processing Dependency: glibc-common = 2.5-18.el5_1.1 for package: glibc Error: No Package Matching glibc.i686 jlc
