Hi Charles!
What I did was I removed /Library/Application Support/TextMate prior to the installation of this bundle. Was that a mistake? There's no mention of having to checkout the bundles first.
both removing /Library/Applications Support/TextMate and/or ~/Library/ Applications Support/TextMate shouldn't matter.
Try installing the Bundle again. Thats the only thing that i can tell you.
