I appreciate the response. It's likely easier to use a
pandoc-citeproc
package right from the repos when it arrives
pandoc-citeproc is now in the F20 updates-testing repo btw.
So if you want you should be able to install it now with
"yum install --enablerepo=updates-testing pandoc-citeproc".

Or if you wait a week then it should reach the stable repos.
Thanks to Ben for reviewing the package. :)
