Regarding gromacs 4.6.5 build failure (mpi compilers)

Hi,
I am trying to build gromacs 4.6.5 on centos 6.5 (i managed to build gromacs5.x.x with intel) and i am facing compilation issue.
The gromacs team hovewer recommends gnu/openmpi compilers instead of intel!! :

It worked,
also: replacing mpiicc with gcc worked!!

seems some issue with mpiicc , is there something i am missing (config flags?), if i replace mpiicc with icc  i get:
 

In file included from /home/soft/cuda-6.0/include/cuda_runtime.h(59),
                 from /home/cc/vfaculty/puneets.vfaculty/GromacsPlumed/gromacs-4.6.5/src/gmxlib/gpu_utils/memtestG80_core.cu(0):

  #error -- unsupported ICC configuration! Only ICC 13.1 on Linux x86_64 is supported!
   ^

so i reconfigured gromacs using intel 2013 compilers (icc version 13.0.1 (gcc version 4.4.7 compatibility)
even then i get the same error :

Any help/hint/suggestion will be very useful.
config logs are attached!
