wha-hey! many thanks to jeff for getting this sorted out, it will be a major breakthrough to have this operational on macosx. macosx is the one OS where pyjd doesn't have a runtime, and it would be a major strategic coup for the project. jeff, would you mind actioning the last little thing? oh - also some clues as to what you did! i'm going to try to repro this on marie's mac-mini, and create a .dmg. l.
