[arch-haskell] Handling cabal-install flags

[Alessandro Pezzoni]

Hello,
I'm trying to add a pacakage for Yi [1,2] to habs (at least to my
working copy) and I'm facing a dilemma, as it uses some cabal-install
flags to change build-depends and exposed-modules, among other things.
Should I heavily patch the cabal file, e.g. by removing some
conditionals, or is there some proper way to handle this?

Thanks,
Alessandro
