I just downloaded c2hs (HEAD version) and tried to run "runhaskell Setup.hs configure" using the ghc 6.8 release candidate (i.e., Cabal 1.2), and got the following error:
Configuring c2hs-0.15.0... Setup.hs: Error: Non-empty library, but empty exposed modules list. Cabal may not build this library correctly
The .cabal file is parseable by ghc-6.6.1 (with Cabal 1.1.6.2). It's unclear to me whether this counts as a c2hs bug or a Cabal bug (maybe the above message should only be a warning?), so I'm cc'ing both lists. Also note that regardless, c2hs will need to be updated to work with base-2.0; when I tried ghc-6.8 with Cabal-1.1.6, I got the following error:
base/state/CIO.hs:71:7: Could not find module `System.Cmd': it is a member of package process-1.0, which is hidden
