thanks for this

I just tested your patch with a fresh install of Ubuntu and it doesn't work 
pix_opencv still depends both on opencv 1.5 and 2.3
it's a shame but I'll fix this later
the svn version works on ubuntu after installing legacy packages : 
sudo apt-get install libopencv-dev libcv-dev libhighgui-dev libcvaux-dev

libopencv-dev is version 2.3.1
the others are legacy and install among others cv.h

concerning, pix_opencv_blobtrack, which version of opencv are you using ?
check it with : echo $(pkg-config --modversion opencv)

cheers

FYI it does not build on archlinux (with opencv2).

I fixed some of it with the following patch:
https://gist.github.com/gusano/5814205

and now all externals build fine except for `pix_opencv_blobtrack` which gives the following error:


blobtrack.h: In function ‘CvFGDetector* cvCreateFGDetector1()’:
blobtrack.h:20:113: warning: control reaches end of non-void function [-Wreturn-type]
