[Rd] Rmpi on CentOS

After setting the LD_LIBRARY_PATH to use the OpenMPI libs, I now get a
different error when I try to load Rmpi

> require(Rmpi)                                                                                           
Loading required package: Rmpi
librdmacm: couldn't read ABI version.

libibverbs: Fatal: couldn't read uverbs ABI version.
CMA: unable to open /dev/infiniband/rdma_cm
WARNING: Failed to open "OpenIB-cma" [DAT_INTERNAL_ERROR:].
This may be a real error or it may be an invalid entry in the uDAPL
Registry which is contained in the dat.conf file. Contact your local
System Administrator to confirm the availability of the interfaces in
the dat.conf file.

I don't have this problem with Fedora 11 and I'd have thought there
would be little difference with CentOS (64 bit).  

I thought it might be because there aren't librdmacm or libibverbs
rpms installed, but that's not the case.  There are no -devel rpms
to go with them, but I doubt that's the problem since they're not on
the Fedora installation either (IIRC).

Is there something else that needs to be specified?
