Well, it's not that much of a hoop. If you start LightTable from the command line, via "open /Applications/LightTable.app", then it gets your environment parameters, including PATH, which is the important one.

I tried to create a ~/.MacOSX/environment.plist file per the instructions here[1], but that didn't seem to work and I haven't bothered to fiddle with it more.
