Additionally, I was able to work around this (and a similar error in libTIFF.dylib) by symlinking to the corresponding dylib in /System/Library/Frameworks.... However, I then reached the following {{{ In [1]: import gnucash.gnucash_core --------------------------------------------------------------------------- ImportError Traceback (most recent call last) /Users/reubano/<ipython-input-1-d3675276f3f3> in <module>() ----> 1 import gnucash.gnucash_core /opt/x11/lib/python2.7/site-packages/gnucash/__init__.py in <module>() 4 # instead of 5 # >>> from gnucash.gnucash_core import thingy ----> 6 from gnucash_core import * 7 ## @file 8 # @brief helper file for the importing of gnucash /opt/x11/lib/python2.7/site-packages/gnucash/gnucash_core.py in <module>() 29 # @ingroup python_bindings 30 ---> 31 import gnucash_core_c 32 33 from function_class import \ /opt/x11/lib/python2.7/site-packages/gnucash/gnucash_core_c.py in <module>() 23 fp.close() 24 return _mod ---> 25 _gnucash_core_c = swig_import_helper() 26 del swig_import_helper 27 else: /opt/x11/lib/python2.7/site-packages/gnucash/gnucash_core_c.py in swig_import_helper() 19 if fp is not None: 20 try: ---> 21 _mod = imp.load_module('_gnucash_core_c', fp, pathname, description) 22 finally: 23 fp.close() ImportError: dlopen(/opt/x11/lib/python2.7/site- packages/gnucash/_gnucash_core_c.so, 2): Symbol not found: __cg_png_create_info_struct Referenced from: /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/ImageIO.framework/Versions/A/ImageIO Expected in: /opt/x11/lib/libpng14.14.dylib in /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/ImageIO.framework/Versions/A/ImageIO }}} and there is no libpng14.14.dylib in /System/Library/Frameworks.
