 get the source version through svn :
 
 svn co https://pure-data.svn.sourceforge.net/svnroot/pure-data pure-data
 cd pure-data/trunk/externals/pix_opencv
 
+you need a working build toolchain
+
 pix_opencv depends on OpenCV 2.x and >1.5 (for old externals)
 
 ===== GNU/Linux ===== 
 
-(actually only tested in GNU/Linux Ubuntu)
-this new version requiered OpenCV 2.3, available with apt-get since 12.04 :

+# (actually only tested in GNU/Linux Ubuntu)
+# this new version requiered OpenCV 2.3, available with apt-get since 12.04 :
 apt-get install libopencv-dev libcv-dev libhighgui-dev
 
-for other systems, you must build the lib from source, see this :
-http://opencv.willowgarage.com/wiki/InstallGuide
-
-get the _SOURCES_ of the pd you are using
-and of the GEM that you are loading
-( it might not work if the version
-is different )
-
-cd into the package folder :
-
-  cd pix_opencv
-
-configure the package with the appropriate command for your system :
-
-  ./configure --with-pd=<path to pd _sources_> --with-gem=<path to gem _sources_>
-
-for example :
-
-./configure --with-pd=/usr/local/pd --with-gem=/usr/local/pd/gem
-
-then, compile it :
+# for other systems, you can build the lib from source, see this :
+# http://opencv.willowgarage.com/wiki/InstallGuide
 
-make clean
-make
+# get the source : 
+svn co https://pure-data.svn.sourceforge.net/svnroot/pure-data/trunk/externals/pix_opencv pix_opencv
 
-and put the *.pd_linux and *.pd files somewhere in Pd's path.  You can add the
-current directory to the pd search path through Media->Preferences->Path
+cd pix_opencv
+make 
 
+# To use the binaries you can either put them into the same folder as your patch or to add this folder to the search paths of Pd
 
 ===== MAC OSX (intel and powerPC) =====
 
+# install opencv with fink :
+fink install opencv-dev
 
-first install openCV MacOS framework 
-   download openCV private framework from http://www.ient.rwth-aachen.de/cms/software/opencv/
-   copy the provided OpenCV.framework folder in your /Library/Frameworks/ directory ::
-	cp -Rf /Volumes/OpenCV\ Private\ Framework/OpenCV.framework /Library/Frameworks/
-this will only install OpenCV 1.5
-
-you need OpenCV 2.x to use recent pix_opencv externals
-you will find a step by step how to install it on Mac OSX here : 
-http://opencv.willowgarage.com/wiki/Mac_OS_X_OpenCV_Port
-but this document is quite old...
- 
-get the _SOURCES_ of the pd you are using
-and of the GEM that you are loading
-( it might not work if the version
-is different )
-
-cd into the package folder ::
-
-  cd pix_opencv
-
-configure the package with the appropriate command for your system :
-
-  ./configure --with-pd=<path to pd _sources_> --with-gem=<path to gem _sources_>
-
-for example :
-
-./configure --with-pd=/usr/local/pd --with-gem=/usr/local/pd/gem
-
-then, compile it ::
-
-  make clean
-  make
-
-and copy the .pd_darwin to your externals folder ::
+# if you don't have fink, you can build it from source by following this guide :
+# http://opencv.willowgarage.com/wiki/InstallGuide
 
-  cp *.pd_darwin /Applications/Pd-0.40.3-extended-20080315.app/Contents/Resources/extra/Gem/ for example
+# then get the sources and compile :
+svn co https://pure-data.svn.sourceforge.net/svnroot/pure-data/trunk/externals/pix_opencv pix_opencv
+cd pix_opencv
+make PD_PATH=/path/to/pdextended-app/Contents/Resources/
 
+# PD_PATH should be ended by something like that : Pd-0.43.4-extended-20121231.app/Contents/Resources/
