The configure script does an inplace substitution in orca.pl.in for the
ps command, so this would explain the problem.

Otherwise you can find this in orca:

# Print a message on the statistics of this running process.
sub running_stats {
  return unless $opt_verbose;

  my $ps_self = '@PS_SELF@';
  if ($ps_self) {
    $ps_self =~ s/PID/$$/g;
    system($ps_self);
  }


and change the $ps_self variable to the setting appropriate for your
system.

Best,
Blair
