Because it provides a library. The library component doesn't function
without ghc. So we use the general strategy with libraries. To use them
you need:

    * a compiler
    * any dependencies must also be available.

haskell-pandoc package also provides the pandoc binary too, which
doesn't need these things.

I could also tweak the cabal2arch script to call the generated package 
'pandoc' if that would help (we already have special cases for other
application/library packages, like xmonad and hscolour).

Probably makes sense to update to 1.0 and use cabal2arch to generate it.
