I\'ve just gone to installed RoR on my snow leopard mac.. and found the rails gem was already installed..
is this normal? Does it need updating?
Does this get in
Yes, the rails gem is already installed along with Snow Leopard, because you installed developer tools, it's very normal.
But it's a little bit old, you need to update it.
TextMate did not bundle any RoR stuff with this. TextMate just included a lot of bundles which mainly consists of Python and Ruby scripts, if you do not have ruby, textmate will not work.
However, TextMate is originally made on Tiger 10.4, which bundled Ruby 1.8.2, and Snow Leopard bundled Ruby 1.8.7, so TextMate's bundles is not fully compatible with Snow Leopard Refer to this and get some fix for these issues:

And also make sure you always keep your RoR bundle to the latest SVN is also a good habit
