[PD] problems compiling pix_opencv in OSX (Was Re: pdp_opencv & pix_opencv new development)

[Jack]

Argghh, I didn't try the objects and they freeze (or sometime crash)  
my PD.
The objects draw perfectly under PD but i got this error :
error: [pix_opencv_contours_convexity]: cannot handle this format  
(1234567) !
or
[pix_opencv_haarcascade]: ERROR: Could not load classifier cascade
Why ?
Any idea ?
