OK, thanks for the gentle push. After a bit of digging, I decided that
the takusen link looked like a darcs repository, and I downloaded
darcs and got takusen. I installed GHC 6.6 in a spare VM (no PC round
I can install stuff on just now, I'll do this properly later). On the
assumption that the takusen.cabal file means I should look at Cabal, I
had a dig and found the incantation "runhaskell setup.hs".

I got the error:

F:\takusen>runhaskell setup.hs

    Could not find module `Distribution.Compat.FilePath':
      it is hidden (in package Cabal-1.1.6)

I assume this relates to the note in setup.hs "For ghc-6.6 you will
need to first install Cabal-", but as I got GHC from a Windows
binary install, I'm not sure where to go from here. I found the Cabal
webpage and downloaded Trying to install it, I got the

OK, that's as far as I can go. Remember, what I *want* to do is to run
some SQL against my database to get some data into a Haskell program.
I'm not up to debugging a Cabal install. (At this point, if I was
doing this for "real work", I'd be off to the Python website like a

Can anyone help? I promise, I will document what I end up with!
