avoid reinstalling gem (if its already installed?

Is there a way to have rubygems not reinstall a gem if the latest
version is already installed?

For example, I want the second 'install' below to simply say 'already
installed' and exit successfully.

rsanheim@ares:~ $ sudo gem install bacon
Successfully installed bacon-1.0.0
1 gem installed
Installing ri documentation for bacon-1.0.0...
Installing RDoc documentation for bacon-1.0.0...

rsanheim@ares:~ $ sudo gem list|grep bacon
bacon (1.0.0, 0.9.0)

rsanheim@ares:~ $ sudo gem install bacon
Successfully installed bacon-1.0.0
1 gem installed
Installing ri documentation for bacon-1.0.0...
Installing RDoc documentation for bacon-1.0.0...

thanks,
- Rob

I'm going to be setting up machines with stock set of gems, and then
periodically refreshing them with a revised list. I'd like to have
gem skip the ones it already has for efficiency.

So I take it I would have to use the gem api to do this?

No, your "stock set of gems" should be a gem that only has
dependencies on other gems.

Seriously, like our users who have this crazy notion that web pages
should take less than two minutes to load. If only we could use Jedi
mind tricks on them...

It's like they think programmers are actually supposed to make life
easier for them, or something.
