Some older versions of libibverbs do not have `ibv_event_type_str`, leading to compilation failures on older machines, irrespective of whether they could ever support usNIC anyway. If we encounter any other build issues related to "old verbs" then we should just cause the usnic BTL to disqualify itself when it encounters "old" traits. Thanks to Paul Hargrove for reporting the issue: http://www.open-mpi.org/community/lists/devel/2014/02/14056.php Reviewed-by: Jeff Squyres <jsquyres@cisco.com> cmr=v1.7.5:reviewer=ompi-rm1.7 This commit was SVN r30674.
