So do I - there's a bunch of RPMs in the system packages that are a
pain to install from source (if they're on PyPI at all - assorted
Fedora specific utilities aren't). But virtualenv doesn't work that
way by default, and the web/PaaS focused devs that write a lot of the
upstream "best practices" guidelines aren't typically fans of distro
provided packages because they're too old (scientific users often have
a similar complaint).

Playing peacemaker between the "move fast and break things" and "if
it's less than 5 years old it's still just a fad" schools of thought
is one of the things that makes packaging so "interesting" ;)

Cheers,
Nick.
