While tracking down an emacs problem, I noticed the following while compiling emacs:
Dumping under names emacs and emacs-21.3.1 715504 pure bytes used ./emacs -q -batch -f list-load-path-shadows This site has duplicate Lisp libraries with the same name. If a locally-installed Lisp library overrides a library in the Emacs release, that can cause trouble, and you should probably remove the locally-installed version unless you know what you are doing.
/usr/share/emacs/site-lisp/tree-widget hides /usr/share/emacs/site-lisp/slime/tree-widget
We use Emacs21's tree-widget.el library and we have bundled it with SLIME so that it will be available under other Emacsen. The warning here is saying that you have two tree-widget.el's and Emacs's own one is taking precedence over SLIME's copy.
I'm not sure if there is a better way to handle this.
