[Pythonmac-SIG] Zope.Interface won't build on 10.4

[brad.allen@omsdal.com]

Maybe I should take this to one of  the Twisted or Zope lists, but this 
appears to be a Mac-specific issue so I thought it worth mentioning here. 
The problem is that Zope Interface 3.01 won't build on Mac OS 10.3 using 
either the stock Python 2.3 or Python 2.4.1 (error transcript at the 
bottom).

 A Google search of the problem turned up a discussion on one of the Zope 
lists about this, but I didn't understand how to implement the suggested 
solution.  One message in the thread suggests the problem is that Python 
was compiled under gcc 3.x and Mac OS 10.4 defaults to using gcc 4.x, and 
that using gcc select can fix the problem. Any thoughts on how to do that?

Here is the error transcript. A similar error happens when running 
setup.py install.
