Thanks for sorting that out, Dmitry - the latest github version (d7eaeed) 
builds fine.

No, '-lgomp' would get found ok. My problem was that there was no directive 
for libgomp to be linked in.

Yes, I could see:
Checking if can compile with OpenMP... yes

That test script does compile ok - and builds to executable iff the '-lgomp' 
argument is provided.
The fix for me was as easy as adding the '-lgomp' (to the LIBS arg that gets 
given to Makefile.PL), and everything then works fine.

Cheers,
Rob
