I'm not able to reproduce the problem building a similar configuration
on a ppc G4 other than using Developer Tools 3.1.2. There is also no
problem when using 2.6.1 from the python.org OS X installer. The test
seems pretty basic.
A few things to try:
First, make sure this is the real problem by trying this snippet:
/usr/local/test/python/bin/python2.6
>>> from ctypes import cdll
>>> from ctypes.util import find_library
>>> sc = cdll.LoadLibrary(find_library("SystemConfiguration"))
>>> x = sc.CFStringCreateWithCString(0, "HTTPEnable", 0)
Presumably, if your original test failed, this snippet should fail, too.
If you can, download the python.org 2.6.1 OSX installer and make sure
your original test works with it. If so, perhaps you don't need to
build your own? That install works on both Intel and PPC. One
difference: it is built with MACOX_DEPLOYMENT_TARGET=10.3, meaning it
will work on systems >= 10.3 but if you really need 10.5 only there
might be some side-effects that are important to you.
Otherwise, you might want to try rebuilding on the PPC from scratch
(i.e. an empty build directory) using the 2.6.1 tarball. By "same
build" on Intel CPU, you do mean you've rebuilt on PPC? You could build
a "fat" Universal python on either architecture that will work on both
but you'll need to add a few more options to configure to do that.
