[pluggo] Using Jitter in a Pluggo vst

Dear all,
I'm trying to export a Jitter patch as VST, and following errors occur:

error: jit.gl.handle: unable to load object bundle executable
error: jit.pwindow: unable to load object bundle executable
ecc..
for every jitter object included in the patch.


I already copied the "jitter-externals" , "jitter-shaders" and "max-startup" folders into "/Library/Application Support/C74 Plug-in Support".


I'm using Mac-Intel with OSX 10.4.10, MaxMSP 4.6.3, Jitter 1.6.3, Ableton Live 6.0.7.

What am I forgetting?

Thank you very much for attention

Carlo
