Selenium and Python on Snow Leopard

Question

I'm trying to use the stock Python (2.6.1) on Snow Leopard with Selenium. Being quite new to Python, I'm a at a bit of a loss for what I've done wrong, as this exact same process worked just fine on my ubuntu box:

1. sudo easy_install -U selenium
2. Create a simple test with Firefox Selenium UI, and export it as Python WebDriver (as mytest.py)
3. $ python mytest.py (which results in:

This error message:

E

One thing worth noting is that when I ran "sudo easy_install -U selenium", I did get a warning:

Check your Firefox binary location first. Does it placed at here: /Applications/Firefox.app/Contents/MacOS/firefox ?
