Antoine,

thanks for your kind reply! Please see my comments below,

Thanks!

Debian Linux is offering me the following packages 
	libopencv-apps0d
	libopencv-calib3d2.4v5
	libopencv-contrib2.4v5
	libopencv-core2.4v5
	libopencv-features2d2.4v5
	libopencv-flann2.4v5
	libopencv-gpu2.4v5
	libopencv-highgui2.4-deb0
	libopencv-imgproc2.4v5
	libopencv-legacy2.4v5
	libopencv-ml2.4v5
	libopencv-objdetect2.4v5
	libopencv-ocl2.4v5
	libopencv-photo2.4v5
	libopencv-stitching2.4v5
	libopencv-superres2.4v5
	libopencv-ts2.4v5
	libopencv-video2.4v5
	libopencv-videostab2.4v5
	libopencv2.4-java
	libopencv2.4-jni
which pulls in a total of 44 packages. I installed them all, loaded
using [declare -lib pix_opencv] and can not create an object like
[pix_opencv_threshold].

No need on my side for now, thank you. 
How would apple users install and use pix_opencv by the way? You
mentioned that you included a libopencv binary with the external?

Can you check which libopencv-packages you have installed on that
computer?

All the best,
Peter
