Did you make sure that Pyverbs was recompiled as part of rdma-core 
rebuild? It looks like you've newer rdma-core with older Pyverbs structs.

Also, if you have multiple python versions make sure that Pyverbs was 
installed under the version you're using.

I don't see these inconsistencies, can you please provide which heads 
you're looking at in case you still seeing this?
