Bug #1350: gem method with version dependency fails
http://redmine.ruby-lang.org/issues/show/1350

Author: Luis Lavena
Status: Open, Priority: Normal
Category: core, Target version: 1.9.1
ruby -v: 1.9.1-p0 darwin9/mingw32

Been trying to use 1.9.1 with certain gems, but it seems that the gem command is broken when a version dependency is specified.

See the following results:

        from /opt/local/bin/irb-1.9.1:12:in `<main>'

It seems that doesn't matter what gem or version is specified, gem method fails.
