Depends on what you mean. For my purposes, the answer is yes.

I use gem for package management, but crown[1] to construct a 
self-contained set of lib, ext, and bin dirs so that my program can run 
without any reference to rubygems.

The following command builds the self-contained dirs that contain 
everything I need for what I do with sinatra:

$ crown -v mydir sequel nokogiri sinatra json thin pg

All those gems are now available as ordinary libraries under mydir/. 
There's no chance that a gem update will break your code. You can check 
in the gem stuff alongside your project code so that you have a snapshot 
of exactly what libs you were using at that version.

Running crown will also output something like:

PATH=/home/username/project/somedir/bin
RUBYLIB=/home/username/project/somedir/ext/json/ext:/home/username/project/somedir/lib:/home/username/project/somedir/ext

You can paste this into your main app file so that it knows where to 
find the libs. Also, you can remove RUBYOPT='-rubygems' from your env.
