Resolving dependencies on Windows

[khalid-hussain]

I'm getting the following error on Windows. I've installed it from source, installed GraphViz, and set the path for the latter's bin directory as well; I know it is working as dot -V gives me correct output.

Resolving dependencies...
cabal.exe: Could not resolve dependencies:

I've also tried running the command after using the cabal update command. Any ideas?

Thanks for your time.

Dupe of #14 unfortunately.

I need to try a release again. When I tried before, the new version of GHC wasn't compatible with all dependencies (graphviz in particular) and I saw no easy way to fix it. Maybe this has changed.
