Here's the console output:

Not sure how best to debug..

I had the same issue and found that the Leap Motion library that comes with the raindance code (https://github.com/ThibaultReuille/raindance/blob/master/Lib/LeapSDK/lib/LeapPython.so) was the culprit. Checking with otool, LeapPython.so is linked against the system python version, while the graphiti binary is linked against a different python version. In my case, I was using the version of python from MacPorts.

$ otool -L LeapPython.so 
LeapPython.so:
    @loader_path/LeapPython.so (compatibility version 0.0.0, current version 0.0.0)
    /Library/Frameworks/Python.framework/Versions/2.7/Python (compatibility version 2.7.0, current version 2.7.0)
    @loader_path/libLeap.dylib (compatibility version 0.7.0, current version 2.1.3)
    /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 56.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0)

$ otool -L graphiti
graphiti:
    /opt/local/Library/Frameworks/Python.framework/Versions/2.7/Python (compatibility version 2.7.0, current version 2.7.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)
    /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 1153.18.0)
    /System/Library/Frameworks/GLUT.framework/Versions/A/GLUT (compatibility version 1.0.0, current version 1.0.0)
    /System/Library/Frameworks/OpenGL.framework/Versions/A/OpenGL (compatibility version 1.0.0, current version 1.0.0)
    /System/Library/Frameworks/OpenCL.framework/Versions/A/OpenCL (compatibility version 1.0.0, current version 1.0.0)
    /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 120.0.0)

I had to modify the Leap Motion library to be linked against the MacPorts python. To do this, I used the install_name_tool utility.

$ install_name_tool -change /Library/Frameworks/Python.framework/Versions/2.7/Python /opt/local/Library/Frameworks/Python.framework/Versions/2.7/Python LeapPython.so

Now LeapPython.so should be linked against the MacPorts python.

$ otool -L LeapPython.so 
LeapPython.so:
    @loader_path/LeapPython.so (compatibility version 0.0.0, current version 0.0.0)
    /opt/local/Library/Frameworks/Python.framework/Versions/2.7/Python (compatibility version 2.7.0, current version 2.7.0)
    @loader_path/libLeap.dylib (compatibility version 0.7.0, current version 2.1.3)
    /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 56.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0)

Now you can rebuild graphiti with make clean && make and then run it.

Thanks @evenfowler -- worked like a charm. If you have python installed by homebrew the way to fix the LeapPython.so is with these commands:

cd dataviz/raindance/Lib/LeapSDK/lib/

install_name_tool -change /Library/Frameworks/Python.framework/Versions/2.7/Python /usr/local/Frameworks/Python.framework/Versions/2.7/Python LeapPython.so

And then rebuild graphiti:

cd dataviz/graphiti

make clean && make

Anyway, that worked for me. 👍

Confirmed this works, thanks guys!

Did: brew install python
Got the same crash. (I have LeapMotion not installed)

Result: Python.framework was missing completely in /usr/local/Frameworks/ and in /Library/Frameworks/.
Tried:
cd /dataviz/raindance/Lib/LeapSDK/lib
install_name_tool -add_rpath /usr/local/Frameworks/Python.framework/Versions/2.7/Python LeapPython.so

Result: Python link was created. graphiti still crashes. Any idea?

Sys Specs:
Python 2.7.10_2
pip 7.1.0
OSX Yosemite 10.10.4

Solution: Disable Leapmotion. From:
