The OpenGL package uses a ./configure script which needs sh.exe and
various other programs. Cabal is trying to run sh.exe but it cannot find
it.

To build the OpenGL package on Windows you need to build it from within
an MSYS shell (which provides sh.exe and the other required tools).


There's also a ticket for the bad error message:

#403 Bad error message when running ./configure fails to find sh
http://hackage.haskell.org/trac/hackage/ticket/403

It should be very easy to improve the error message. Patches welcome.
