I get the "cannot configure unix" error for: - happstack-util - happstack-state - happstack-ixset - happstack-server - happstack In other words, everything except happstack-data.

Well, happstack-util is a dependency for the rest of the packages you listed, so you might be better off focusing your efforts there.

It requires unix-compat to build. What does "cabal install unix-compat" give you?

If that's what's breaking you can try "cabal install unix-compat-0.1.2.1" and then "cabal install happstack-util". Version 0.1.2.1 appears to be the most recent version of unix-compat that doesn't specify version bounds on the unix package, which is what you're having trouble with.

If it works let us know.

Thanks for the help! Tom

Also, I'm pretty confused by all of this - unix-2.4.0.0 should build on GCH 6.10. Folks have been saying they've had bad luck installing it separate from a GHC install, though, so I don't know if I should recommend it. Antoine
