It would be great if there were an automated or semi-automated way of generating a MacPorts Portfile from a HackageDB package, along the lines of dons' cabal2arch. Has anyone been working on such a thing? And, are any haskell-cafe readers MacPorts committers?

Gregory Wright handles the ports of GHC, alex, happy, haddock, and others.

In my experience thus far, MacPorts feels like a poor match for Cabal. As far as I can tell, you get at most one active installation of a given port, which means you can't use MacPorts to manage packages for multiple Haskell environments (GHC and Hugs, stable GHC and development GHC, etc.), and after a GHC upgrade, any installed Haskell packages will still be installed, even though the new GHC can't see or use them.

That's exactly the same situation as with Gentoo. We provide a ghc-updater program that re-installs all the existing libs for the new ghc. Gentoo also only provides libs for ghc. Duncan
