my problem with: install intel fortran compiler on ubuntu

Hi,

I am trying to install fortran in ubuntu. I have followed the instructions given in http://ubuntuforums.org/showthread.php?t=1082782, but I am facing some problems. The first one is when I try the step 1, which is "sudo apt-get install rpm build-essential". The result is as following:

Reading package lists... Done
Building dependency tree
Reading state information... Done
build-essential is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
acroread:i386 : Depends: acroread-bin:i386 but it is not going to be installed
rpm : Depends: librpm2 (>= 4.9.0) but it is not going to be installed
Depends: librpmbuild2 (>= 4.9.0) but it is not going to be installed
Depends: librpmio2 (>= 4.9.0) but it is not going to be installed
Depends: librpmsign0 (>= 4.9.0) but it is not going to be installed
Depends: rpm2cpio
Depends: rpm-common (= 4.9.1.1-1ubuntu0.2) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

May you please help me to solve this problem?
