I think Rick must be using one of the snapshots.  In the current
sources there is a getrusage() function that returns a structure like
this:

  octave:3> getrusage ()
  ans =
  {
    nvcsw = 170
    nswap = 0
    ixrss = 22
    nivcsw = 35
    msgrcv = 0
    inblock = 648
    minflt = 447
    stime =
    {
      usec = 179584
      sec = 0
    }

    msgsnd = 0
    isrss = 4
    utime =
    {
      usec = 131760
      sec = 0
    }

    idrss = 168
    majflt = 52
    maxrss = 1272
    nsignals = 0
    oublock = 11
  }

but only if your system has the getrusage system call.  Also in the
current sources, cputime() is implemented in an M-file by calling
the built-in function getrusage().

In any case, cputime has always been implemented using the getrusage()
system call, so it does not work on all systems.  If you know of
systems that do not have getrusage() but do have ways to get some (or
all) of that information using different system functions, please let
me know.

I do know that Solaris has getrusage() in the BSD compatibility library,
but Octave's configure script isn't currently looking there.
Something more to fix...
