How do I load from /usr/share/xemacs/* with xemacs-21.5.26 ?

Ok, I have downloaded the sources for 21.5.26, configured, built and installed under /usr/local on a W2k system with cygwin. Xemacs seems to run ok, but I don't know how to teach it to load all the modules that I normally use. I added this: (setq load-path (cons "/usr/share/xemacs/xemacs-packages/lisp/clearcase/" load-path)) and it then successfully finds clearcase, but do I have to do this for all modules I need to load? Shouldn't there be a base directory I can set so that all packages/modules under it can be found? I have tried (setq module-load-path (cons .... but that does not seem to work either. Sorry, I am a lisp newbie :-/ -- Manfred (1) (initialization/error) An error has occurred while loading /home/mbartz/.xemacs/init.el: Cannot open load file: "clearcase" Backtrace follows: signal(file-error ("Cannot open load file" "clearcase")) # bind (path handler filename nosuffix nomessage noerror file) load("clearcase") # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...)
