Find in Path not working with external libraries rvm gems

When I right-click on an External Libaries entry and select Find in Path, the path is never populated in the Find window.

Example:  Right-click on External Libaries: [gem] authlogic (v2.1.6, /Users/myname/.rvm/gems/ree-1.8.7-2011.03@boxy/gems/authlogic-2.1.6)

it should set the "Directory" to /Users/myname/.rvm/gems/ree-1.8.7-2011.03@boxy/gems/authlogic-2.1.6

however it always just goes to "Whole Project", and the Directory text box never gets set :(
