If ps didn't work, then you need to make sure the kernel is approximately
the same date of sources as ps.  Bedcause of the many changes in the kernel,
you have to keep such utilities up to date.

Additionally, third party stuff such as top must be recompiled as there is
no way to keep binary compatibility between Mach VM and UVM on those
programs.

Make sure that your sources in /usr/include/sys (kernel stuff) are up to
date.  It's likely that they are not.  Doing a "make includes" in /sys
should solve that problem--but be warned, if you're going to do this, you
may not be able to compile everything without updating the whole system.

Welcome to tracking -current.  :-/
