A couple of rebuilds later....

Rebecca> I still don't have a menu for Rebecca> Options>Customize>Emacs> This continues to be the Rebecca> error-message. I removed all the files in the Rebecca> Xemacs-21.0 directory except for info before rebulding This seems to be the right thing to do, because ... Rebecca> (1) (error/warning) Error in menubar filter: Rebecca> (void-function custom-put). ... `custom-put' is an obsolete function not used anywhere in the core lisp in xemacs-21/lisp. It was marked obsolete in 21-b39, now grep doesn't find it at all. So it looks like somewhere you're picking up an old menubar configuration. Do you have a lisp/x11/ directory? There now should be only one subdirectory of lisp/, the lisp/term/ directory (and possibly a lisp/CVS/ directory if you're using CVS). However, if you're patching or using CVS without the `cvs update -P' option, you could have old files hanging around that somehow end up on your path before "real" menubar-items.el[c]. This persists under `-q' and `-vanilla', right?
