I recently updated from OS X 10.8 to OS X 10.9. It looks like the upgrade removed the previous version of Python and all the libraries that were installed. I am trying to re-install Scrapy on OS X 10.9 but I keep getting an error using both pip and easy_install.
Here is the error message I am encountering.

/private/tmp/pip_build_root/lxml/src/lxml/includes/etree_defs.h:9:10: fatal error: 'libxml/xmlversion.h' file not found

#include "libxml/xmlversion.h"

         ^

1 error generated.

error: command 'cc' failed with exit status 1 

Does anyone know to resolve this or have a work around?
