The gem resource used to determine if a gem is installed based on the exit status of the `gem` command, however that command will return zero if the package was found or not. This patch checks to ensure that the `gem list` command actually includes the gem name or is empty to determine if the gem is in fact installed. If the gem command returns something other than a `0` exit code, then it'll skip the resource. Signed-off-by: Keith Walters <keith.walters@cattywamp.us>
