The bundle gets errors when trying to find "#{ENV['TM_BUNDLE_SUPPORT']}/template_html_header.rhtml"
It may be that you have a partial and/or outdated svn checkout.
I suggest you do http://wiki.macromates.com/Troubleshooting/RevertToDefaultBundles
Thanks Allan. I tried what you suggested, but I'm still getting the same error after I reverted to the default bundles.
I've been using Macports to run ruby 1.8.7 on my mac, when I took macports out of my PATH and tried it again it worked! So it seems to be an issue with the Macports version of ruby. Any ideas of how I could fix this?
