RVM / downgrading bundler gem

Question

I have the following interesting scenario:

I've install ruby 1.9.2 via RVM and it came prepackaged with bundler 1.1.4.

My application requires bundler 1.0.15.

I've tried running the following:

gem uninstall bundler

I get the following:

INFO:  gem "bundler" is not installed

Any thoughts how can downgrade my bundler?

Thanks.

Found the solution.

Apparently rvm installs it's gems in the global gemspec which is visible to all gemspecs.

So by doing:

rvm use 1.9.2@global

And followed by:

gem uninstall bundler

Does the trick.

This can be also shortened to:

rvm @global do gem uninstall bundler
