Same problem with eqc.hrl here, once I replace 'make' with 'gmake'
since I'm on FreeBSD.

It's a different approach than jsongen, but I have a similar setup of
a JSON API for an Erlang codebase.
I'm using aeon* to convert JSON <=> Erlang records and sanitize the
json input along the way.
Since QuickCheck (and PropEr) can use the type info in Erlang records,
you could:
 1) Write Erlang records that correspond to your JSON
 2) Use QC/PropEr to generate the Erlang records
 3) Use aeon to convert the Erlang to JSON and call your API with it

*aeon: https://github.com/garret-smith/aeon

Yes, aeon is my own project.  Hopefully others can use it too.
