Yes, your numpy is fine, but your matplotlib is an older branch, and although it is still being maintained it looks like it is not in sync with changes to numpy going from 1.1 to 1.2. I hope Fedora 10 has switched to the current branch, 0.98.x. In any case, however, matplotlib changes fast enough that it may be worthwhile building your own. It is very easy to do on a linux machine once the necessary headers are in place. Typically this involves installing several *dev or *devel packages--I don't know the specifics of Fedora packaging.
