To be pedantic, you've no guarantee that env will be in /usr/bin
(although granted that it will be the vast majority of the time). The
real wart here is that if you have multiple interpreters installed, say,
in /usr/bin and /usr/local/bin, then /usr/bin/env picks the python
that's associated with your PATH. This can lead to bad surprises if the
script runs in an interactive shell vs., say, a CGI script or a cron
job, where the PATHs are almost certain to be far more restrictive,
particularly if you have a highly customized interactive shell.
Unfortunately, there's truly no magic bullet here when the script itself
depends on a certain version of Python.
