Ssi Mohamed,
Try to install the latest version of cmake and use it in compiling both HDF5 and OpenMC. HDF5 needs also to be compiled by use of mpich2 (i.e. export FC=mpif90)

Please note that in version 0.7.1, it is possible to compile with HDF5 and MPICH/OpenMPI together without necessarily using parallel HDF5. I would suggest updating your version of OpenMC and then trying to compile again.

Best,
Paul
