I ran into simialr problems some time ago and blogged about it
here:

Not sure if your problem is exactly the same, but my solution might
point you in the right direction.

BTW, the haskell-cafe mailing list may be a better place for questions
like this. It seems to have a larger readership and is more discussion
focused while this list is more for announcements.

Cheers,
Erik
