It seems like that was an error in the package itself. This [question](http://stackoverflow.com/q/17361047/912144) and its answer have the solution.

Thank you for the pointer. I am in the process of updating libpandoc to work with pandoc 1.11 (actually above 1.10) where I came to a build issue that I'm not sure how to resolve.

Loading package regex-pcre-builtin-0.94.4.6.8.31 ... linking ... ghc: /home/XXXX/.cabal/lib/regex-pcre-builtin-0.94.4.6.8.31/ghc-7.4.1/HSregex-pcre-builtin-0.94.4.6.8.31.o: unknown symbol `utf8_table4'
ghc: unable to load package `regex-pcre-builtin-0.94.4.6.8.31'

Trying to reinstall regex-pcre-builtin with cabal gives a warning that it may break pandoc.

The offending source code is this:

{-# LANGUAGE TemplateHaskell #-}

module LibPandoc.Instances where

import Data.Data
import Data.DeriveTH
import Text.Pandoc
import Text.Pandoc.Shared

$( derive makeTypeable ''ReaderOptions )
$( derive makeData ''ReaderOptions )
$( derive makeTypeable ''WriterOptions )
$( derive makeData ''WriterOptions )
$( derive makeTypeable ''HTMLMathMethod )
$( derive makeData ''HTMLMathMethod )
$( derive makeTypeable ''ObfuscationMethod )
$( derive makeData ''ObfuscationMethod )

Can you see anything wrong there?

Thank you again for the help,
Shahbaz

but I'm not sure when it was last updated.
