Unless your IB libraries are in the default search path, you need to tell
LAM's configure where to find them. There's an option --with-rpi-ib=PATH
that accomplishes this task.
Note that the IB support in LAM is quite unoptimized and only works with
Mellanox VERBS, which is also quite old. If you're migrating to a new
cluster, you'd be better off moving to the more modern Open Fabrics
instead of mVAPI and moving to Open MPI instead of LAM at the same time.
