Great! That fixed solved the problem. I now have ical sync!

Couple of small things, nothing big to worry about:
1) When I've checked off a to do item in ical and then sync, it succeeds in syncing back with the textmate file, but I also get this error:
/Users/lawrencegoodman/Library/Application Support/TextMate/Bundles/GTDAlt.tmbundle/Support/bin/gtdalt_ical_synchronization.scpt: execution error: iCal got an error: NSReceiverEvaluationScriptError: 4 (1)

It doesn't seem to affect functionality, but I thought you might want to know about it.

2) In the instructions, it says: 
These commands don't seem to be working. Have they been eliminated?

Thanks again for all the help.
