I am not an autoconf expert, however could there be another interpreter.h? 
(llvm has an interpreter.h) You check for existence, right?

I check out from http://hg.code.sf.net/p/octave/parallel and go do "make 
release". I have no special env-variables set. Octave is installed under 
/usr/local/Cellar/octave/4.0.3/ and symlinked to /usr/local/bin etc. The path 
is set such that /usr/local/bin has preference. The mkoctfile setting are 
attached in output0.txt.

I made those modifications and committed to the local repo. Results are 
attached in output1.txt.
