brew doctor shows warning when building with --64bit option

[sauberfred]

I successfully installed julia with the 64bit option on OS 10.9.1.
But running brew doctor gives me:

Warning: Some installed formula are missing dependencies.
You should `brew install` the missing dependencies:

    brew install arpack-julia openblas-julia suite-sparse-julia

Run `brew missing` for more details.

Don't worry about this; it's an artifact of how the julia formula is setup. These warnings are harmless, I'll leave this issue open to remind me to see if I can silence these warnings somehow.
