I assume you mean lock down so that the gem cleanup command won't remove 
particular versions.

There is no direct way to do this in RubyGems.  However, you could 
create a gem of your own that installed no software but did depened on 
the versions of the software you needed.  It is pretty trivial to create 
gems, so this is not hard.  As long as your "lock down" gem is 
installed, the cleanup command won't remove the referenced gem versions. 
(caveat: technique untried, but can't think of a reason it wouldn't 
work).
