Upgrading to the Latest getmail on Cygwin

I've been trying to get a backup of GMail working on my Windows PC using getmail on Cygwin.  I've run across a couple of problems so I decided to upgrade to the latest version of getmail.  The default install of getmail on cygwin was  4.36.0.  Latest version from the developer was 4.39.1.

Installed a new version like this:

1. mkdir newgetmail
2. cd newgetmail
3. wget http://pyropus.ca/software/getmail/old-versions/getmail-4.39.1.tar.gz
4.  tar xvf getmail-4.39.1.tar.gz
5. cd getmail-4.39.1
6. python setup.py install
