I have a perplexing problem. I have used mac version 10.9, anaconda 3.4.1, python 2.7.6.

Developing web application with python-amazon-product-api. i have overcome an obstacle about installing lxml, referencing clang error: unknown argument: '-mno-fused-madd' (python package installation failure).

but another runtime error happened. Here is the output from webbrowser.

Exception Type: ImportError
Exception Value:    
dlopen(/Users/User_Name/Documents/App_Name/lib/python2.7/site-packages/lxml/etree.so, 2): Library not loaded: libxml2.2.dylib
Referenced from: /Users/User_Name/Documents/App_Name/lib/python2.7/site-packages/lxml/etree.so
Reason: Incompatible library version: etree.so requires version 12.0.0 or later, but libxml2.2.dylib provides version 10.0.0

Not sure how to proceed and have searched here and elsewhere for this particular error. Any help is much appreciated!
