TextMate ... WTF?

Like any good Ruby developer working on a fresh bit of code, you eagerly start setting up to run your first test and get hit with this in TextMate:

`blank_slate_method_added': stack level too deep (SystemStackError)

Ouch. Screeching halt. The root cause for this comes from a conflict between TextMate's version of Builder and the system-installed version. There are a couple solutions floating out there - either remove the TextMate-bundled version entirely or drop this in your test file:

$:.reject! { |e| e.include? 'TextMate' }

I prefer this method as it doesn't have any noticeable side effects anywhere I've used it. This appears to be the official solution to date.
