I can add in head of query function something like :
if (!mca_btl_openib_component.cpc_explicitly_defined)
return OMPI_ERR_NOT_SUPPORTED;

Well, it's "fixed" in that Pasha turned off the error message. But
the same issue is undoubtedly happening.
I was asking for something a little stronger: perhaps we should
actually have IBCM not try to be used unless it's specifically asked
for. Or maybe it shouldn't even build itself unless specifically
asked for (which would obviously take care of the run-time issues as
well).
The whole point of doing IBCM was to have a simple and fast mechanism
for IB wireup. But with these two problems (IBCM not properly
installed on all systems, and ib_cm_listen() fails periodically), it
more or less makes it unusable. Therefore we shouldn't recommend it
to production customers, and per precedent elsewhere in the code base,
we should either not build it by default and/or not use it unless
specifically asked for.
