CouchDB compilation failure

CouchDB (branch 2.0.0-RC4) fails to build with error:

{{==> couch (compile)

I am on RHEL 6.7 hence js185 is not available. I am also experiencing problem building js185 from source but not with js24. You may see the path from the log has changed to 'mozjs-24', from changing the src/couch/rebar.config.script file.

Regardless, related to COUCHDB-3312, is couchDB to be compiled on js185 ONLY, or later version like js24 would also work?

If the latter, what is the problem with my compilation failure?
