What type of error are you seeing here?  Also what version of
OFED/MVAPICH2 are you using?

I suggest using --with-rdma=gen2 or you can simply drop this option
since gen2 is the default.  The gen2 interface will outperform the
udapl interface.  I also suggest that you use mvapich2-1.5.1p1 since
the need for specifying -D_XOPEN_SOURCE=600 is removed and may have
caused problems with your application.

With mvapich2-1.5.1p1 you should be able to use the following line...
./configure --prefix=/usr/mpi/intel/mvapich2-1.5.1p1
--enable-sharedlibs=gcc 'CC=icc -i-dynamic' 'CXX=icpc -i-dynamic'
'F77=ifort -i-dynamic' 'F90=ifort -i-dynamic'

Yes.

I hope that you find this information useful.
