Previously, trying to resolve the dependencies of a keg would raise an exception if the formulae for any of the dependencies could not be found (e.g. if it had been moved to another tap). This commit updates the dependency finding logic to catch these exceptions, and fall back to comparing names and taps of formulae, which should give the correct behaviour. Fixes #1586.
Homebrew's Formula API
This is the (partially) documented public API for Homebrew.
The main class you should look at is the {Formula} class (and classes linked from there). That's the class that's used to create Homebrew formulae (i.e. package descriptions). Assume anything else you stumble upon is private.
You may also find the Formula Cookbook and Ruby Style Guide helpful in creating formulae.
Good luck!
