Until portage actually can do this in a better way, you would have to multiply ebuilds (probably each with common import and a one-line variable setting) (I don't know the exact restrictions on portage version strings):
Right that'd be possible, to include the slot information into the ebuild name, but unfortunately that would be against gentoo versioning policy. We're supposed to have the ebuild name be the package name and use slotting for the other stuff. We have talked to portage devs about our problem. We'll have to wait, or all jump ship to NixOS which can do this stuff properly.
One day, you may even want mtl for other compilers...
Indeed, we'd want to slot on the compiler (and for ghc the compiler version) and on the library version. Then we only want to satisfy other haskell library dependencies from within the same compiler slot. Duncan
