pyxml is loaded from an ugly "hook" in xml/__init__.py, which looks for 
a package named _xmlplus, and if it exists, munges sys.modules so that 
the module "xml" actually points to _xmlplus. This confuses 
bundlebuilder (and users).

So you need _xmlplus AND xml. Check whether bundlebuilder adds them 
both to your app. If not, use dummy imports to make sure that they 
included.

Or try Just approach (renaming _xmlplus to xml), or try replacing all 
references to module xml in your source with _xmlplus.

I think that these tricks alone still won't work, as some pyxml modules 
load plugin modules (e.g. parsers) dynamically and might not be 
recognized by bundlebuilder. So you have to load these plugins 
explicitly.
