I also tought about looking into the pd-l2ork project (currently i'm trying to make it load Gem library), and trying to install pd-extended 0.43 to see if there was some change that could be helpful, but the autobuild for maverick doesn't seem to work.

Regarding pd-l2ork, did you install pd-l2ork full install or just the pd-l2ork itself without extended libs? If latter, libs will not work and many will crash due to fundamental changes to how pd works so you would need to install pd-l2ork full (see instructions online for building your own). FWIW, Gem works just fine over here (as do all the libs I tested so far with the exception of Gridflow).

HTH
