Can one safely assume that

   http://hackage.haskell.org/packages/archive/PACK/PACK-VER.tar.gz

untars into a PACK-VER directory containing that package? I hope that this is 
the case. So our package description file can look like this:

   core base 2.1
   core haskell98 1.0
   extra http://www.cs.york.ac.uk/fp/darcs/polyparse 
ftp://ftp.cs.york.ac.uk/pub/haskell/polyparse/polyparse-1.0.tar.gz
   extra OpenGL 2.1
   ...

Earlier you've mentioned some sharing of libraries. Could you elaborate a bit 
how this should work in detail? I only have a very vague idea, and I am not 
sure if this is a must or only a nice-to-have.

Cheers,
