Hackable Mercurial Can't Find os Module

[Jensen, Aaron]

I'm trying to get hackable Mercurial working [1] on Windows 7 x64. I've got  Mercurial 2.5.4 installed with TortoiseHg 2.7.2.

My initial problem was the packaged hg.exe couldn't load the Python DLL. I found an old mailing list thread with this exact error [2], where the solution was to add the included hg-python26 directory to my PATH variable. I did that, but now I'm getting this error:

    > .\hg.exe in
    'import site' failed; use -v for traceback
    Traceback (most recent call last):
      File "F:\Build\hhg\hg", line 10, in <module>
        import os
    ImportError: No module named os

When I add the -v option for traceback, the error message is the same.

What additional setup steps do I need to do?
