Because they are both languages, I put the Pads modules in Language.Pads.XXX and the Forest modules in Language.Forest.XXX. I have a single development space with a directory Language with subdirectories Pads and Forest. Now I want to to be able to install these libraries with cabal. The place where it seems like I am supposed to put the cabal file is the directory containing the Language directory, but that means I need one cabal file for Pads and another for Forest. Rearranging my directory structure to separate the two packages is a pain because the files are under version control in CVS.
So your problem is maybe more a problem of CVS rearrangement than a
Haskell packaging problem? If you have direct access to the CVS
repository you might rearrange the '*,v' files in the CVS repository as
you need. This rearrangement will not be logged by CVS, of course, but
that is a known deficiency of CVS.

I don't know enough about your languages, but putting Pads and Forest
into two packages sounds reasonable. I would move them into separate
directories if possible.
