You will need all the official repos for the packages specified. But a
working super basic Debian Wheezy system can be running fpm relatively easy.

It took a while to get to this point because there is a lot of information
out there that does not work.
Most of this stuff should apply to the associated Ubuntu systems that will
be based on Debian Wheezy.

And without delay:
