Hi Matthieu,

For posterity, here's what worked. I am sure there's a better way to do this
but right now I don't want to know! ;-)

[DEFAULT]
library_dirs = /usr/lib
include_dirs = /usr/include
libraries = pthread, m

[mkl]
library_dirs = /opt/intel/mkl/10.0.2.018/lib/em64t
lapack_libs = mkl, mkl_lapack
mkl_libs = mkl, guide

Thanks for your help,
Anand
