Installation via pip behind a firewall

[ghost]

I realise this is something of a long shot, but my team have been experiencing issues trying to install librabbitmq behind a corporate firewall, specifically the machine in question is unable to reach GitHub, so we can't clone rabbitmq-c.

Right now as far as I can see our options are to either get a firewall exception or to manually clone, copy and build the project locally.

Essentially what I'm asking is do we have a third option, i.e could rabbitmq-c be included in a PyPi (which we have a proxy for) distribution?
