This is indeed the case:

C:\sf\py2exe\tests>c:\python20\python.exe
Python 2.0 (#8, Apr 25 2001, 22:09:02) [MSC 32 bit (Intel)] on win32
Type "copyright", "credits" or "license" for more information.
>>> import xml
>>> xml
<module '_xmlplus' from 'c:\python20\_xmlplus\__init__.pyc'>
>>>

As you can see, 'import xml' actually loads _xmlplus and puts this
into sys.modules under the name 'xml'.
This can also be done by the packed executable, however, the _xmlplus
package must be available for this to work, and the bundling process
does not find it.

Use the -p command line flag 'python setup.py py2exe -p _xmlplus'
to include the whole _xmlplus package into the exe.
