I'm trying to install a package to the Haskell Platform in Cygwin. It requires the websockets package, for which the most recent version is 0.9.0.1.
My command looks like:
cabal install websockets
And I get the following error message during the build (it downloads fine):

I have a default install of Cygwin x64 and Haskell Platform x64 on Windows 7 Pro x64. Is there a workaround to this? Or am I missing some configuration?
I have the same cabal update issue mentioned at http://www.haskell.org/pipermail/beginners/2010-June/004357.html, where my updated cabal version is not being used (I keep getting notified about a newer version), but the install command keeps saying the new version installed fine. I'm not sure if that has something to do with this...
