Great, I'm glad to hear it. :-)

Yes. The default was wrong and different distro want to put them in
different places anyway so it has to be configurable.

Yes, we've been having similar issues with doc generation in ghc-6.8.1.
There are several bugs open about it. They're not going into a versioned
ghc doc directory by default and the inter-package links are not getting
created. We hope this will be fixed in 6.8.2.

Oh that's a good idea. We should do that in gentoo too.

Yes, that's what we do for Gentoo. We have a program that generates
ebuild scripts directly from the hackage index. We've got about 150
hackage packages via this route. You might like to look into adapting
our code:
darcs get --partial http://haskell.org/~gentoo/hackport/

It's not been fully updated to deal with the new features in Cabal-1.2

Sounds sensible.

No problem. Sorry for the upheavals.
