Working (?) flags.mk file for compiling LMF March 2014 release (http://ccpforge.cse.rl.ac.uk/gf/project/lmf/frs/?action=FrsReleaseView&release_id=355) on Federoa / Xeon with GNU libraries (removed hard coded links to Intel MKL etc.)

# LibXC compiled & installed by hand. There's also a version in the distribution repository.
