The file in the zip archive is not marked as executable (you can try
running the path in the error message yourself to get the same
result). This appears to be a genuine problem with the file in the Git
repository.

However, it would be better to use a <runner> to tell 0install that
this is a Python program (and which version of Python to use). See
e.g. https://github.com/0install/0compile/blob/master/0compile.xml#L28
for an example of using <runner> to run a Python (2) program. Then it
doesn't matter whether the file is executable or not and it will work
on all platforms.

Use "0install add NAME" instead of "0install run" if you want a
launcher script (called NAME).
