Thanks all - As i updated to Lion, I needed to install x code 4.1 to get the correct files behind the scenes for the bundler to install all of the correct bundles. All working sweet now!

I tried a number of different solutions, but what finally worked for me was simply using a different version of 1.9.2.

I was having the same problem with 1.9.2-p280, but when I switched to 1.9.2-p180, I was able to install with out problems. Can't tell you why this worked, but it did.
