OK, I just tried that on your machine. You just have to replace
/use/local/lib with /usr/lib.

It links fine and starts running.
There's some issue with the stack which results in

$ ibv_pingpong
Couldn't get context for mthca0

but that's probably some setup issue you'll be able to
figure out.


Roland, is there some way to get the plugin
directory out of the libibverbs library?
