AFAIK, there is no OpenSM requirement for these libraries.

This was likely due to IPoIB needing to be enabled on the default
partition. From the 1.3 opensm man page,

PARTITION CONFIGURATION
       The default name of OpenSM partitions configuration file is 
       /etc/opensm/partitions.conf. The default may be changed by using
       --Pconfig (-P) option with OpenSM.
...
       The  following  rule  is equivalent to how OpenSM used to run prior to
       the partition manager:

        Default=0x7fff,ipoib:ALL=full;
