I've got the package status script running well now. Check it:
http://www.galois.com/~dons/arch-haskell-status.html
You can sort on the data you're interested in, e.g.
* built against old cabal2arch
* popular on hackage
* popular on AUR
(generated by the 'report' function in Distribution.ArchLinux.Report).
Cheers,
Don
