nhc doesn't really work w/ cabal at all (or is it vice versa? ;) )

For Hugs, we can install in a local directory, but registering doesn't
really have the same behavior in Hugs than it does in GHC.  With GHC
we have this level of indirection that help us to find packages.

In GHC, I can say --prefix=~/, and after I register with --user or
whatever, ghc can find that package.

With Hugs, last I heard, Hugs will only find packages installed in
standard places; it doesn't have that level of indirection.

So in a sense, the package registration for Hugs still doesn't quite
make sense, although I haven't really followed Hugs lately.  Whether
it will make even less sense if we try to impose some kind of
"in-place" package config file?

Maybe Ross can let us know if anything has changed.
