How to install Numpy?

Hi all,
As part of a bigger install (openPnP, which requires openCV, which requires numpy as shown here... http://docs.opencv.org/2.4.10/doc/tutorials/introduction/linux_install/linux_install.html#linux-installation. The machine is not connected to the internet, so I'm doing this manually. I'm down past the halfway mark on that list and trying to install numpy, but the installation instructions don't make much sense to me. It mentions Fortran, Ubuntu versions, Windows, and free compilers/mingw-v64, but none seem to apply to my setup (just Debian Wheezy). I can't try one of the Ubuntu methods as this machine is offline, so I can't use apt-get as specified in those sections. Also, there is no makefile.
Any clue what I should do next?
Thanks.
