No, I think it's another problem.

What happens here is that configure tries to compile some utility
program (utils/pwd/pwd) using an existing ghc, which of course is
impossible when you're porting ghc a platform not already running
ghc. Similar problems are located in libraries and the Cabal-generated

For the utils/pwd/pwd problem, I really don't understand why that
thing is required at all, since it does little more than get the
pwd and add some slash or backslash escaping/quadrupling depending
on the argument passed to it.

You may try the patch below (and don't forget to re-run autoconf).

Note that this is the quick hack I did for OpenBSD. If the forward slash
hack of util/pwd is really required (for Windows builds?), something

hardtop=`pwd | tr '\\' /`

would be more appropriate. And the other sanity checks I deleted
may be necessary in some cases, too, but I really don't see the
point in them.


ps: IMHO, libaries/ifBuildable.hs should die a horrible death, too.
It can replaced with a few lines of shell commands..
