Sorry, today’s post won’t be pretty and certainly not for people who are not familiar with Debian and installing. It’s basically just a short summary for me. But feel free to email me or post a comment if you need assistance.

Get the Intel Fortran and CC compiler. If you use them for non-commercial purposes it is free to download them.

Installing the stuff:
Make sure the ia32-libs package is installed, when running an amd64 port.
apt-get install ia32-libs
This is not the default on Debian!
