Are you talking about bundle commands or user scripts (⌘R)?

In either case, I guess the issue is that you have gems installed in ~/.gems (or whatever the folder is) which will be picked up by all versions of ruby!?!

Though no bundle commands actually use ruby gems, so, ehm… which bundle commands actually fail?

OK, so I suspect the issue is that you have set RUBYLIB, RUBYOPT, or similar in your shell. When you launch TextMate from your shell, this environment is inherited and would explain why the ruby TextMate use would get your third party gems…

Presently I use a blacklist for the inherited environment, I’ll add RUBY* to this list, although it might perhaps be better to move to whitelisting the variables we do wish to inherit.
