By the way, I filed a bug on this issue:

No, actually, my report isn't about that issue at all. I'm not
talking about making an entirely statically built application. I'm
talking about a statically compiled Open MPI with a dynamically
linked application and OFED. Take a look at the output of mpicc -
showme -- it's not adding *ANY* -l or -L options for InfiniBand.
This is something wrong with Open MPI's configure, which has
changed since v1.2. On v1.2, the same commands result in:
[10:54] brbarret@odin:pts/27 v1.2> mpicc -showme
gcc -I/u/brbarret/Software/x86_64-unknown-linux-gnu/ompi/devel/
include -pthread -L/usr/local/ofed/lib64 -L/u/brbarret/Software/
x86_64-unknown-linux-gnu/ompi/devel/lib -lmpi -lopen-rte -lopen-pal
-libverbs -lrt -lnuma -ldl -Wl,--export-dynamic -lnsl -lutil -lm -ldl
[10:55] brbarret@odin:pts/27 examples> make ring_c
mpicc -g ring_c.c -o ring_c

Hi all -
There's a problem with the OpenIB components when statically
linking. For whatever reason, the configure logic is not adding the
right -L and -l flags to the mpicc wrapper flags.

and many more, obviously.
Good luck,
