Changes (by duncan):

  * difficulty:  normal => hard (< 1 day)
  * summary:  implement hugs-pkg? => make hugs, nhc, lhc and Cabal agree on
              installed package info
  * milestone:  => _|_

Comment:

 This isn't tht hard but needs changes in Hugs and a bit in Cabal and then
 testing and a new hugs release. The scheme with installed package info
 files should work for hugs, nhc and lhc. On the Cabal side of things the
 same implementation can be used for each.
