Howdy,

At the time of the error it isn't your file being read in but hyperref.sty.

Did you do any manual updating (e.g., updating hyperref manually)?

When then did you install MacTeX-2010? Please go to the System Preferences->TeX Distribution preference pane and see which TeX distribution active. Unfortunately, TeX Live 2010 can no longer be automatically updated (will someone tell me I'm wrong?). Updating things like hyperref or kvoptions is really tricky because there are too many interdependent packages.

Your best bet is to download and install MacTeX-2011 (since you now on OS X 10.5 it will work) from <http://www.tug.org/mactex/2011/> and, once it's installed, immediately run TeX Live Utility to get all the updates available between the time TeX Live 2011 was released and the time it was frozen (in preparation for the release of TeX Live 2012---still in pretest mode). That should give you a completely consistent set of files.

Don't be afraid, you can always change back to TeX Live 2010 via the TeX Distribution preference pane.
