The ruby18 shim is in the Bundle Support bundle.
Either you have an outdated version of this bundle (can happen if you install it locally and do not update it, as it’ll then eclipse the managed version) or it could be your PATH — you say you understand the latter, but you did not provide any info about how you have it setup.
To ensure you have default bundles see https://github.com/textmate/textmate/wiki/Reverting-To-Defaults
If you need to alter PATH then see http://blog.macromates.com/2014/defining-a-path/
