Using brew with Ruby 1.9.2

I'm trying to get ImageMagick with Homebrew, but I keep getting errors. Then I did a "brew doctor" and I get:

Ruby version 1.9.2 is unsupported.

Homebrew is developed and tested on Ruby 1.8.x, and may not work correctly on Ruby 1.9.x. Patches are accepted as long as they don't break on 1.8.x.

==>/usr/bin occurs before /usr/local/bin This means that system-provided programs will be used instead of those provided by Homebrew. This is an issue if you eg. brew installed Python.

Consider editing your .bashrc to put: /usr/local/bin ahead of/usr/bin in your PATH.

Can this really be true?

If so, what are my other options here?
