Yes. They will need to be deb/rpm/arch/slack/whatever-ified anyways,
because that's how the Linux distributions that are going to ship them work.

Yes, this is an issue in practice, and that's why the packagers have a
say in what libraries and in what versions you are adding to the
global-requirements. We have to use versions that are the least problematic.

You can use any minifier with the django-compress plugin that Horizon
uses (django-xstatic has nothing to do with it). You just define the
command (or a filter written in Python) to use for every mime type.
But I assume that ngMin is written in the Node.js language (which is
would have to convince your fellow system administrators to install
node.js on their production servers. Violence may result.
