Hmm. sem_wait should be provided by some operating system library.
Usually the threads library used (I think). And that one should have
been found by configure, I believe.

You could look up in the operating system documentation in which
library sem_wait is defined. Then, add that to LIBS while building.
Maybe lam (and OpenMPI?) should check for it?
Hope that helps,
