They don't have to "bleed" anything. Everything, including the python 
interpreter, and 3rd party libraries can be included in a single 
executable. Here is an example script for pyinstaller that rolls 
evertyhing into one file (this is what I use to roll up my passerby 
program at

setenv TEMP temp

set pythonexe='c:/Python23-Enthought/python'
set pbydir='z:/Code/pby/current/'

rm *.pyc

rm -rf ./temp/ ./passerby/
mkdir temp

$pythonexe --onefile --tk --noconsole  \
                        --icon $pbydir/../icons/passerby.ico \
       $pbydir/ passerby/passerby.spec
$pythonexe passerby/passerby.spec

You can control installation with innosetup.
