There's another FAQ on GNU site that, I think, addresses the Pandoc/Hakyll
"You have a GPL'ed program that I'd like to link with my code to build a
proprietary program. Does the fact that I link with your program mean I have
to GPL my program?
Not exactly. It means you must release your program under a license
compatible with the GPL (more precisely, compatible with one or more GPL
versions accepted by all the rest of the code in the combination that you
link). The combination itself is then available under those GPL versions. "
