21.4.0 build failure on Solaris

Built from a full tarball on Solaris 2.7. Installation file is attached. I also downloaded the xemacs and mule sumo packages from a week ago and installed them. When temacs does its thing, it complains as follows (the full log is also attached): Loading /apps/public/XEmacs/lib/mule-packages/lisp/egg-its/dumped-lisp.el... Loading egg-sj3-leim...
