I am using TeXLive 2007 as installed by the MacTeX installer, so that
is one difference, though my console output looks to be very similar.
Since it is a missing character, it could be the dreaded corrupt font
cache problem. You might try and grab something like Font Finagler or
Font Nuke, delete all your font caches, and see if that fixes it. See:

http://www.jamapi.com/pr/fn/

Good luck and let us know if deleting font caches fixes the problem.

By the way, you can install TeXLive 2007 with the MacTeX installer and
you will be able to use either gwtex or TeXLive by switching
distributions with the preference pane that gets installed.
