I've been having a similar problem compiling NumPy with MKL on a cluster with a site-wide license. Dag's site.cfg fails to config if I use 'iomp5' in it, since (at least with this version, 11.1) libiomp5 is located in 

	/scinet/gpc/intel/Compiler/11.1/072/lib/intel64/

whereas the actual proper MKL 

	/scinet/gpc/intel/Compiler/11.1/072/mkl/lib/em64t/

I've tried putting both in my library_dirs separated by a colon as is suggested by the docs, but python setup.py config fails to find MKL in this case. Has anyone else run into this issue?
