Is this in the normal Windows %PATH%, or just the cygwin $PATH?
ghc/runghc is a normal Windows program so using it to run Setup.hs,
it'll only look at the Windows %PATH% and knows nothing about cygwin.

How did you resolve this? Sounds like you managed to get it building
anyway.

This is just an error in the Haskell code.

Had you managed to build by that time? ie fixing the above problem? It's
not going to be able to install if it did not build.

Did you get it working in the end? Is there anything from all this that
needs fixing or improving in Cabal?

The current state of the liskell repo build perfectly for me using just

$ cabal install

Admittedly this is on Linux not Windows.
