Final patch available at: http://support.frictionalgames.com/entry/88/
I am working on a new build that should alleviate the rather odd launching problem everyone has been encountering. It also syncs up the build with all the fixes from the latest Windows hotfix build. (improving ATI compatibility, which doesn't seem to be affecting Mac users, but may in future OSX releases)
On the launching issues, the machine which consistently ran into the launching issue you have been seeing, has not encountered it since last night when I put the new build on the machine.. I'll be testing it every so often throughout the day Just to be sure while I prepare the DMG/Installation instructions.
Please watch this thread as I will be posting the patch in the next day or two.
Here is the initial Mac Patch. Currently it is a torrent hosted on my machine (I am adding a second seed on a faster connection right now).

(Oh and any help in making the installation instructions clearer.. I'd be much appreciative. That is one of my Inkscape
specials.. I'm a programmer, not an artist).
