This sounds reasonable. However, do you have examples of dependencies that CABAL can express but pacman can't? (I was under the impression that the difference was that CABAL allowed more terse expressions, not that it allowed more.)
See the issue reported by https://github.com/archhaskell/cabal2arch/issues#issue/19. PKGBUILDs can only specify dependency requirements with one inequality (<, >, <= or >=) whereas Cabal can specify any Boolean combination of inequalities.
Have you seen this? http://mailman.archlinux.org/pipermail/pacman-dev/2010-December/012065.html It would enable "parsec >= 3.0 || == 2.1" to be translated to "haskell-parsec>=3.0 || haskell-parsec=2.1". It obviously won't be included any time soon, but it would provide a long-term solution. Regards, Xyne
