Yeah, configure seems to be failing without any error message.

Try doing a
$ runhaskell Setup.hs clean
first and then
$ runhaskell Setup.hs configure -v3
$ runhaskell Setup.hs build

and if it still fails you should be able to see what it was doing last.
If it is indeed still failing then send me the full output of
$ runhaskell Setup.hs configure -v3
and the version of Cabal you're using and the full package you're
working on (preferably as a link to a darcs repo or as a tarball). Don't
send it all to the whole mailing list though or we'll annoy people :-).
