You didn't need to file in the OpenGL bindings before regenerating the VM ?

I need to rename all the directories inside Content ?

I follow all what you say and i have a tea-squeak VM binaries linked to libffi 
(version 2) and 
libGL with all plugins internally generated, but still have the same error as 
before. Maybe it's a problem with my 3D card, because the Squeak3D.log says : 
OpenGL initialization failed No OpenGL visual found!

Thank you Bert for your kindly help.
