I should install some packages for a molecular dynamics package(LAMMPS) in Ubuntu 9.10, I have an error and can't do that!

this is the command line I write:
"sudo apt-get install build-essential fftw-dev tcsh mpich2 gfortran"

and this is the error:

I know that Sourceforge banned Iran, and I'm an Iraninan citizen. It seems the error is related to a file named : andale32.exe . I downloaded this file. but I don't know what to do with the file.
Besides I want to know how to apt-get files from terminal(from sourceforge)? Do I need a proxy? I'm really confused and I'm a beginner in Linux. Please help me...

Any political problems with sites available to you aside . . .

- try synaptic package manager . . . yes, a little bit of a learning curve to start, but it does work very well once you get the hang of it.
So, use it instead of the apt-get install ?

Synaptic will show what is available . . . nice for beginners.
It'd be interesting if synaptic would say something is not available for some unique reason like borders/trade restrictions . . . I have no idea about that.
