I have a package that depends on the multiprocessing package, which

So, for only those people using python versions before 2.6, I want to

Is this possible?
Yes. Write your setup.py to check the Python version, and build up the
requirements in a variable before calling setup().
I'm -1 on this solution.
Please note that *future* fixes won't help the person who asked what
to do right now.
[1] One way to implement conditional requirements is to make use of
Requirement.extras. If setuptools/distribute supports builtin extras -
such as Py26, Py27, Py30 and so forth .. even Py3x to cover all 3.x
versions - then one can have a [<Py26] section in their install_requires
that would specify requirements specific to versions below 2.6.
It would also need to support platform-specific requirements, and
possibly other options as well.
which, however, means one has to run
setup.py with all its silly hacks (raw_input() anyone?).
Ew. Somebody actually did that? Please identify the culprit so they
can be publicly shamed.
