Thanks for the quick reply. The problem is that I'm not trying to do anything with ps, but cmake internally is doing a popen("ps axo pid,ppid") in Source/kwsys/ProcessUNIX.c to identify any children of a process it is about to kill, and to kill them first. Since this capability doesn't seem critical to cmake operation, I've worked around the need for ps by replacing it with a copy of usr/bin/false for now.
