Just getting started with GEM for some video stuff, want to see what pixeltango can do but can't get anything working, either with examples or trying to put pieces together myself. Everything loads fine and basic GEM stuff seems to work, but opening the pixeltango Two-Layer-Example I get 'stripPath_setup not found' and 'no method for clear' (counter) errors. Loading the loop elements generates more no-clear-method errors; turning on looping gives divide by zero. And so on -- can't get examples to do anything more than display single frames, same results trying to build it myself. Any advice?

This is pd-extended 0.39.3 for PPC Mac 10.4.11; I'd prefer not to step up to the 0.40 release to avoid the X dependency.
