ghc-5.02.2 seems to need gcc-2.95.3, but here we have gcc-3.0.* per default. There IS a gcc-2.95.3 tree around, but how do I tell ghc about it?

You can use 'ghc -pgmcgcc-2.95.3' (unfortunately you can't leave a space between -pgmc and gcc-2.95.3 because of a bug in the command-line handling of this option in 5.02.2). If you build GHC yourself, there's a configure-time option to select which gcc to use, namely --with-gcc=<gcc>. Cheers, Simon
