Build failure under Fedora 21

[Dominick Samperi]

The best way to move beyond the somewhat dated version of the Haskell
Platform that is distributed with Fedora 21 is to install the version
available at http://www.haskell.org/platform instead of the version
installed by yum. This fixes all of the shared library issues that
arise when installing pandoc. Thanks to John MacFarlane (pandoc
author) for this tip.
