Hi, I finally got round to building gtk2hs packages for Fedora Core 5 and they are available now from http://haskell.org/fedora/. In addition to ghc641-gtk2hs-cairo there is also a "virtual" ghc-gtk2hs package which should make upgrading smoother when the ghc version changes: currently it just pulls in ghc641-gtk2hs. Please report any problems here. Cheers, Jens ps I'm going to submit this gtk2hs package to Fedora Extras.
