Yes, pbs_iff is definitely present. Please note that I originally wrote:

More interesting, if the user's PATH is set so that /usr/bin is the first element, the problem goes away. The problem comes back if another element is placed in the PATH before /usr/bin, apparently regardless of what that element is.
