I've uploaded two new Lisp sumo tarballs to the ftp site:
ftp://ftp.xemacs.org/pub/xemacs/packages/xemacs-sumo-1998-12-09.tar.gz
ftp://ftp.xemacs.org/pub/xemacs/packages/xemacs-mule-sumo-1998-12-09.tar.gz
These are somewhat different than the ones Jan made. They don't have
an lib/xemacs prefix, and XEmacs/Mule and non-Mule are separated. If
this is a problem let me know.
These should work with both XEmacs 21.0.x and 21.2.x. If they don't
it is a bug to be fixed.
