[gmx-users] problem compiling gromacs 5.1

[Ana Marija]

For 4.6.7 gromacs MPI_Library flag was necessary as well as for 4.5.5. What
I am asking here is not weather my admins are doing a good job,and also as
you know some things you just got with machine,and sometimes things are not
great,so you have to make a workaround. What I am asking here is what is
the function and is there is a function of mpi_Library flag in gromacs 5.1
and was that flag replaced with a different one in that version?
