Although I am experiencing this problem using a specific domain library (pjsip). Googling this issue show that it is happening to many libraries in python on mac.
I was wondering whether anyone solved this or alike in the past and might share what steps were taken. Note: this python lib works fine on other platforms (posix, win, and earlier versions of mac os x) >>> import py_pjsua Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.5/ lib/python2.5/site-packages/py_pjsua.so, 2): Symbol not found: ___CFConstantStringClassReference Referenced from: /Library/Frameworks/Python.framework/Versions/2.5/ lib/python2.5/site-packages/py_pjsua.so Expected in: dynamic lookup -- http://mail.python.org/mailman/listinfo/python-list
