Error building on OSX - Githubissues

Tried to build pywebkitgtk on OS X Leopard 10.5.7 against webkit-gtk
version 1.1.7 installed via MacPorts.

./configure --prefix=/opt/local
make

Produced this error:

Adding this line to webkit.override above the pygtk/pygtk.h include fixed
the problem and allowed the compilation to continue:
#define NO_IMPORT_PYGTK

But running the demo in demos/tabbed_browser.py produces this error:

Traceback (most recent call last):
  File "demos/tabbed_browser.py", line 30, in <module>
    import webkit
ImportError:

Which I traced down to here:

https://bugs.webkit.org/show_bug.cgi?id=23057

Which I managed to fix with their attached patch & recompiling webkit-gtk:
