A better place to ask a question like this would be on the Python Mac 
SIG forum (http://dir.gmane.org/gmane.comp.python.apple).  The problem 
is that the Apple-supplied Python 2.6 in 10.6 runs by default in 64-bit 
mode and the old Mac Carbon modules are not available in 64-bit mode 
since Apple chose not to support 64-bit Carbon.  That's why those old 
Mac modules are deprecated in Python 2.6 and removed in Python 3.   A 
workaround is to force Python to run in 32-bit mode:

$ arch -i386 /usr/bin/python2.6
Python 2.6.1 (r261:67515, Jul  7 2009, 23:51:51) 
[GCC 4.2.1 (Apple Inc. build 5646)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import EasyDialogs
>>>

or

$ export VERSIONER_PYTHON_PREFER_32_BIT=yes
$ /usr/bin/python
