Python Pmw and cx_Freeze?

I am unable to make an executable from my python program which uses Pmw (Python mega widgets). I use cx_Freeze (through gui backend "Gui2Exe"). Searching Pmw site I've found that it's caused by how the Pmw library checks for modules when ran and it doesn't work when you use py2exe or similar programs because the libraries are in a zip file. More info can be found here: http://pmw.sourceforge.net/doc/dynamicloader.html So they give a solution in that page, under "Freezing Pmw", by providing a script which generates a single standalone Pmw module which you can easily freeze. However, that script uses deprecated code and won't work with Python 2.6 +. I've tried to modify it with no luck.

EDIT: I'd like to mention that just replacing 'regex' with 're' won't work.

# Helper script when freezing Pmw applications.  It concatenates all
# Pmw megawidget files into a single file, 'Pmw.py', in the current
# directory.  The script must be called with one argument, being the
# path to the 'lib' directory of the required version of Pmw.
# To freeze a Pmw application, you will also need to copy the
# following files to the application directory before freezing:
#
#    PmwBlt.py PmwColor.py

Unfortunately, the original file has some problems with tabs and spaces (just look at the while indentation in expandlinks).

I fixed those indentation problems, changed regsub.gsub with re.sub and eliminated the string import, using the string type methods.

After that the script worked perfect:

   Pmw.py has been created.
   Before running freeze, also copy the following file(s):
   C:\Users\joaquin\Desktop\Pmw.1.3.2\src\Pmw\Pmw_1_3\lib\PmwBlt.py
   C:\Users\joaquin\Desktop\Pmw.1.3.2\src\Pmw\Pmw_1_3\lib\PmwColor.py
