[Zope] ZGDChart for Zope 2.4.0

Hi Chui & zope@zope.org'ers, Is there a binary version of ZGDChart for Zope 2.4.0 available anywhere? I tried the 0.5.1 Binary release from Zope.org, but I got the following error: Traceback (most recent call last): File "Products/ZGDChart/__init__.py", line 46, in ? import ZGDChart File "Products/ZGDChart/ZGDChart.py", line 106, in ? from gdchart import * ImportError: Products/ZGDChart/gdchart.so: undefined symbol: Py_Free Any help would be very much appreciated :-) cheers, Chris
