In the same general area. When you upgrade something like bytestring
and have to update everything that was built with it (otherwise you'll
get type errors because the ByteString types from the two different
versions are different) cabal-install is of no help. Since it already
believes that I have those packages installed (correctly) if refuses
to install them again so I have to do it all by hand.

I realise that I should be sending darcs patches, not bug reports, but
a --force to reinstall an already installed package would be great. I
guess, ideally, cabal-install would know to rebuild everything that
depends on x when I upgrade x.

darcs patches might follow if I can get round to it (or the next time
I update bytestring...)

Cheers,
