I say it works perfectly when using the single dynamic library
(lmkl_rt):  MKL=" -L${_mkllibpath} -lmkl_rt -lpthread -lm"
N.B: not sure the -lm is needed, and It builds without it. It seems it
may trigger some issues on. See[0]. Thus I removed it

Here it is. The script is writen for Parallel studio 2016. Change path
accordingly if composerxe 2015.
libRlib and libRblas are build as shared librairies. It build with
static libraries too.
More options can be added to configure.
Best is to source mklvars and compilervars in a script so it won't
polluated your shell environment once the build is done.

No. I was not enable to do it with gcc. More tries are needed with
some variations.
