 This bug has been fixed upstream.  Downloading
 [http://hackage.haskell.org/package/pandoc-types-1.12.4.1/pandoc-
 types-1.12.4.1.tar.gz] and applying the following patch to the Portfile
 solves half of it:

 The only thing is that it requires deepseq-generics
 [http://hackage.haskell.org/package/deepseq-generics-0.1.1.2/deepseq-
 generics-0.1.1.2.tar.gz], and a specific version of that (>=0.1 && <0.2),
 but I don't know how to specify that in the Portfile.

 Attached is a Portfile for deepseq-generics which builds a package which
 allows hs-pandoc-types to build.
