A while back Riku Voipio called for help with missing bits for Debian/armel one of which was GHC. Not knowing Martin Guy was already (privately) working on bootstrapping GHC (an ARM port existed already) I decided to have a go at it. The GHC porting documentation is clearly excellent and resulted in quick success (relatively quick given the slow build hardware). At that time Martin was already far ahead of me. Meanwhile he has made packages available. I have yet to get around to reporting some minor problems GHC upstream and I may also investigate why ghci doesn't work at some point, but basically this means Haskell is available to the EABI crowd :)
