I will try a rebuild by adding -fPIC to the CFLAGS of make.mvapich.gen2.

The modifications I have done to the make.mvapich.gen2 are as follows:

o Set the path for IBHOME, IBHOME_LIB, PREFIX
o I set the compilers I want to user
o Edited the configure line to the following:
    ./configure --enable-sharedlibs --enable-debug \
           --with-device=ch_gen2 --with-arch=LINUX -prefix=${PREFIX} \
           -lib="$LIBS" 2>&1 |tee config-mine.log

The LIBS, FFLAGS, CFLAGS, MPIRUN_CFLAGS get set as follows:

LIBS=-L/apps/packages/OFED-1.4.2/lib64 -Wl,-rpath=/apps/packages/OFED-1.4.2/lib64 -libverbs -libumad -lpthread
FFLAGS=-L/apps/packages/OFED-1.4.2/lib64
CFLAGS=-D_EM64T_   -DEARLY_SEND_COMPLETION -DMEMORY_SCALE -DVIADEV_RPUT_SUPPORT -D_SMP_ -D_SMP_RNDV_ -DXRC -DCH_GEN2 -D_GNU_SOURCE -I/apps/packages/OFED-1.4.2/include -O3
MPIRUN_CFLAGS=-D_EM64T_   -DEARLY_SEND_COMPLETION -DMEMORY_SCALE -DVIADEV_RPUT_SUPPORT -D_SMP_ -D_SMP_RNDV_ -DXRC -DCH_GEN2 -D_GNU_SOURCE -I/apps/packages/OFED-1.4.2/include -O3
