compiling OpenCV on MacOSX 10.6

it works now with macports:

sudo port install -u opencv +python26 +tbb

compiling here along with MacTex...

from http://opencv.willowgarage.com/wiki/Mac_OS_X_OpenCV_Port

svn co https://code.ros.org/svn/opencv/trunk/opencv
cd opencv # the directory containing INSTALL, CMakeLists.txt etc.
mkdir build
cd build
cmake -D CMAKE_OSX_ARCHITECTURES=x86_64 -D WITH_FFMPEG=ON -D BUILD_EXAMPLES=ON -D BUILD_LATEX_DOCS=ON -D PDFLATEX_COMPILER=/usr/texbin/pdflatex -D BUILD_NEW_PYTHON_SUPPORT=ON  -D PYTHON_LIBRARY=/opt/local/lib/libpython2.6.dylib -D PYTHON_INCLUDE_DIR=/opt/local/Library/Frameworks/Python.framework/Headers ..
make -j4
sudo make install

I had to rebuild some ports

sudo port install ilmbase
port provides /opt/local/lib/libIlmImf.dylib
sudo port install openexr
sudo port install libdc1394

and recompile

then could run

cd ../samples/python/
python camera.py

another route is homebrew: http://gist.github.com/519418 / :

$ brew info opencv
opencv 2.1.1-pre
http://opencv.willowgarage.com/wiki/
Depends on: cmake, pkg-config, libtiff, jasper, tbb
/usr/local/Cellar/opencv/2.1.1-pre (96 files, 37M)

The OpenCV Python module will not work until you edit your PYTHONPATH like so:
  export PYTHONPATH="/usr/local/lib/python2.6/site-packages/:$PYTHONPATH"

To make this permanent, put it in your shell's profile (e.g. ~/.profile).
