you have the catalog browser (in Pharo 5)
and this: http://catalog.pharo.org <http://catalog.pharo.org/> in all the rest.
now, if people do not contribute their packages, no tool in the world will help you :)
(you contribute your configurations as explained here: http://catalog.pharo.org/catalog/note-for-developers <http://catalog.pharo.org/catalog/note-for-developers>)
