First, John, thanks very much for the backtrace -- this helps us debug
quickly.

regexp-opt is a function that exists in Gnu Emacs, and seems to be
okay too in XEmacs 21.4.13

A similar report for AUC TeX was made last April:
  http://lists.gnu.org/archive/html/auctex/2005-04/msg00048.html

so the solution seems to be install either the xemacs-base package or
the sumo tarball to get the regexp-opt functionality in your xemacs.
