glew-1.5.2 isn't even in the F12 repos, it's in the rawhide (F13) repo, or on koji
. That's a bit of a reach. Click on the "(info)" link on the clew-1.5.2 package on the site I linked to, then browse down to the "Requires" section. Can F8 provide all that? You're going to have to update Fedora eventually if you want to keep abreast of the newest software packages. Your other option is to try and build the latest version of glew from source code and hope F8 can handle the build requirements for doing that task.
