Hi,
Sorry for the late reply. I tried replicating the issue, but could not.
Could you do a couple of things for me:
1. Could you send me the config logs for the build
2. Were you able to run any other LAM executables such as lamboot or
mpirun. Could you try running a simple hello world program and let me know
whether you see similar results.
