[Twisted-Python] error "limits.h missing" while compiling zope interface in Sumo on mac os x 10.4.6 Py 2.4

[Nitin Borwankar on Twisted-Python list]

Hello Twisted gurus,

Apologies if this is a FAQ - couldn't find answers in the obvious
places. ( list archives, google, ...).

I've been trying to build the TwistedSumo-2006-02-12 package -
especially the ZopeInterface package within, and am getting the
following errors
about limits.h not being found.
This is on Mac OS X 10.4.6 on a PPC powerbook G4 with gcc 4.0, I tried
swicthing to 3.3 via gcc_select and got a different error about gcc
command line switches.
An 'ls' on
/Library/Frameworks/Python.framework/Versions/2.4/include/python2.4/
indicates that indeed there's no limits.h there.
Separately downloading earlier stable ZopeInterface version and building
gave exactly the same error.

Python 2.4 is the default python installed via the MacPython 2.4 dmg.
An older Python 2.3 also exists on the system but 2.4 is ahead in the
PATH.

Any help getting past this appreciated.

many more errors which I guess stem from limits.h not being found
