This page describe how to fulfill libavg dependencies using MacPorts. An alternative method (which uses self-contained dependencies) is described here: MacSourceInstall.

Installing the required dependencies

$ sudo port install boost +python27
$ sudo port install gdk-pixbuf2 autoconf automake ffmpeg libsdl pango subversion \
  libtool libdc1394 librsvg python_select
  • Make sure MacPort has correctly added /opt/local/bin to the PATH (usually on .profile)
  • Switch to MacPort's python 2.7
$ port select --set python python27

Fetching and compiling libavg

$ git clone
$ cd libavg
$ ./bootstrap
$ BOOST_PYTHON_LIBS=-lboost_python-mt ./configure --with-boost-thread=-mt

Compile with (adjust the concurrency parameter to the number of CPU cores you have + 1):

$ make -j3


If everything runs fine, you may run the unit tests. Be aware that at first time startup, fontconfig requires several seconds to initialize its fonts cache:

$ make check


$ make install

Anyway, there is a present issue with the install location, which defaults to /usr/local/lib/python2.7/site-packages/libavg instead of /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages.

In order to circumvent this problem, add the directory to PYTHONPATH:

export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH

Add this line to .profile to make it permanent.
