 Replying to [ticket:220 duncan]:
 > The longer term solution is to allow installing multiple instances of
 the same versions of a package built against different versions of its
 dependencies. This is the functional Nix approach however it would
 probably also require support from ghc.

 Couldn't this lead to an exponential explosion in the number of package
 instances?
