Porting is "simply broken" for various reasons at the moment - in
particular the switch to Cabal for building the libraries broke it. We
knew this at the time, but felt it was more important to make the switch
now and fix bootstrapping later.
For pwd, I imagine the best way forward is to use a C program, I don't
think there are any deep issues there.
