Right.  If you ask chicken-install to install an egg, it'll do so.  It
might skip its dependencies in case they are already installed.
chicken-install might skip fetching/compiling eggs in case they can be
found in the chicken-install cache (typically ~/.cache/chicken-install).

chicken-uninstall is part of the installation of chicken.  It should be
available in the same directory where chicken-install is located.

That probably would be the easiest way.

All the best.
