I also faced this problem with the plugins package. This particular
error comes from the backslashes in the ghc library directory not being
escaped. But even after patching this, I had trouble with missing
imports and some other stuff. It seams that this package is not much
used/tested under Windows. At the end I gave up using it and switched to
hint (like Alberto pointed out before).
