Hello, I found that MKL installs incorrect .pc files for the following variations: mkl64-{,int64}-{dynamic,intel}-openmp*.pc All these files contain references to -liomp5, but this library is located not at MKL libdir, but rather at compiler's lib dir: /opt/intel/composerxe-2013.0.080/compiler/lib/${IARCH}/ This path is not preset in *.pc files, thus link stage fails when affected alternatives are selected. See hpl build log below, which fails when e.g. mkl64-gfortran-openmp is selected as BLAS implementation. This can be fixed by addition of compiler's lib path in *.pc files generation code. See attached patch. Works fine for me, though I want to discuss this patch prior commit since this package is quite important.

Ping. I'll fix this in a week if there are no objections.
