It looks like the code is looking for a PYTHONHOME environment variable. Once I added that environment variable pointing to the hg-python26 directory, hackable Mercurial is working. I've updated the Hackable Mercurial for Windows wiki page [1].

In summary, to get hackable Mercurial for Windows working, I had to:

 1. Add the path to the package's hg-python26 directory to my PATH.
 2. Create a PYTHONHOME environment variable, set to the full path to the package's hg-python26 directory.
