Shapely: OSX (10.10.5) fails to load GEOX framework
I'm running OS X 10.10.5 and python, GEOS and shapely from MacPorts:
from shapely.geometry import Point
FailedCDLL(/Library/Frameworks/GEOS.framework/Versions/Current/GEOS)
Traceback (most recent call last):

I've also tried GEOS from homebrew and kyngchaos' framework (http://www.kyngchaos.com/software/frameworks), but the result is always the same.
Could you, please, advise? Thanks!!

I'm so sorry, but I don't know how to help if ctypes can not find libc on your system.

Many thanks for the answer! It turns out that I needed to unset the environment variable DYLD_FALLBACK_LIBRARY_PATH, after which everything works just fine (the package is brilliant, by the way!). Maybe my experience can be of use to others, as well.

Your experience is definitely useful to others. I had the same problem (on OSX too), and the recommended solution of unsetting DYLD_FALLBACK_LIBRARY_PATH has worked for me too - thanks!
