The Arch (and some other linux maintainers) have made the decision to package all Haskell libraries as separate OS packages and install those as dependencies when you install, say, pandoc. This model of distribution doesn't really make much sense for distributing Haskell binaries, though.
There's a few reasons for this: 1) since most people don't have many Haskell binaries and the few that people use don't share many libraries, 2) Haskell packages are normally statically linked when building executables.
If linux maintainers would simply build/ship pandoc as a single static executable all these issues disappear.
