I'm not well informed about different distros, so I've never heard of SMI, sorry Since you say it's redhat based, it must be able to handle rpms. If you installed it from a cd, gcc MUST be on this cd as well. If not, search e. g. on rpmfind.net
a rpm for gcc, download and install with
rpm -i gcc-3.X.X-X.X.X-iX86.rpm
here's a quick result of the search, this one is for Fedora Core 2, it should work, if not try an RPM for mandrake or suse.
sorry, no binary posts
