All the python scripts start #! python2 (or something similar; I can't
remember and can't check now). On Linux or in a Cygwin shell this causes
the system to run /bin/env to find python2 in your environment. So in this
case it means you do not have the cygwin version of python2 installed.
3 solutions: install cygwin python, use Windows python by typing
/path/to/windows/python <python script>
Instead of
<python script>
, or use Windows command prompt. The 2nd and 3rd assume you have Windows
python installed.
