TextMate and “env: ruby: No such file or directory”

Recently TextMate started throwing an “env: ruby: No such file or directory” error every time I tried to use auto-completion to close tags. Turns out this is because I updated my ruby install, installed the new version to another location and renamed the old version to keep it around (“ruby186″ if you must).

However TextMate was still looking for the old version in the old location. A quick symlink and problem solved.
