Thanks to Jamie!

His advice of doing an OSX upgrade, made pdp_glx create windows under X11! So, Mac OSx 10.2.8 is required for pdp. Does anyone have a helpfile for [pdp_glx ] or does it simply take the same messages as pdp_xv? create, destroy, close and dim(ension) works, but not fullscreen. i tried {fullscreen} {fullscreen 1} so far. Thanks again!

I was trying to fix this with great support from the people from gridflow, but I/we got stuck at doing a "make" (this is again pd_37, gridflow-cvs, apple's X11 beta3, ruby 1.6.7) Does anyone know what this could be? Linker maybe? The error is:
