Patches welcome. Probably switching to the 1.6 API won't be too hard.

Yes. Suppose you change the deps:

hunk ./plugins.cabal 42
-  Cabal >= 1.4 && < 1.5,
+  Cabal >= 1.4,

And then try to compile, you'll see (at least for me):

src/System/Plugins/ParsePkgConfCabal.hs,
dist/build/System/Plugins/ParsePkgConfCabal.o )
