Trying to keep things compiling on my imac (10.4.11)

I'm getting this error now:
GPG_Application.cpp: In member function 'void GPG_Application::stopEngine()':
/System/Library/Frameworks/Python.framework/Versions/2.3/include/python2.3/marshal.h:12: error: too many arguments to function 'PyObject* PyMarshal_WriteObjectToString(PyObject*)'
GPG_Application.cpp:720: error: at this point in file

Are we offically not supporint older versions of python now? :)
