From my newLISP loading on WIN/SketchUp 7 here:
http://www.alh.net/newlisp/phpbb/viewtopic.php?t=2710
There comes the next question:
Sketchup runs also on the MAC.
So it is possible to load the newLISP modul under ruby?
newLISP.so load possible on the MAC with Ruby?
Not sure if this will help but I wrote some C code to load the newLISP dylib into a C/C++/Obj-C app: Calling newLISP from C
Get your Objective newLISP groove on.
