I am using cvs version from 04/16. do you want me to put it online?
these dynamic lib errors seem to be new to gem? at least I did not

don't know.

I have not tested pdp_opencv yet, yesterday I only looked at pix_opencv, 
I tried to compile pdp_opencv, but again, get errors.

hmm, yes, when I try it with pix_grey, pd crashes.
