Bug description:
Currently (as of 11.04, and I suspect in 11.10), several packages I've
discovered will potentially break if you have a non-system Python
executable on your PATH, e.g. using virtualenv or a custom-built
Python. As per the Debian Python Policy (I can't find a similarly
thorough document for Ubuntu),
> The preferred specification for the Python interpreter is
/usr/bin/python or /usr/bin/pythonX.Y. This ensures that a Debian
installation of python is used and all dependencies on additional
python modules are met.
> Maintainers should not override the Debian Python interpreter using
/usr/bin/env python or /usr/bin/env pythonX.Y. This is not advisable
as it bypasses Debian's dependency checking and makes the package
vulnerable to incomplete local installations of python.
I think this is reasonable, and also supported by the majority of the
Python scripts in my /usr/bin directory.
This also has potential security implications, i.e. someone with only
user-level access could override the system Python in a user's
~/.bash_profile and install a malicious version of certain package
dependencies.
