If you try installing Intel Fortran Compiler on Ubuntu 10.10 Maverick Meerkat or 10.04 Lucid Lynx or Karmic Koala, it is going to throw the error:
error while loading shared libraries: libstdc++.so.5

The original libstdc++5 package is no longer available with the Ubuntu 9.10 repos. So for 32 bit system you would have to get it from Debian Repository.

Install it and you are good to go if you are using the 32 bit OS.

For 64 bit it is a bit complicated, and you have to follow some additional steps first install libstdc++5 64bit and then do the following (the remaining steps might be skipped, for Maverick Meerkat I only had to install the file linked above and everything worked fine, so I skipped remaining steps, check this before attempting the remaining steps):

wget http://security.ubuntu.com/ubuntu/pool/universe/i/ia32-libs/ia32-libs_2.7ubuntu17.1_amd64.deb

dpkg-deb -x ia32-libs_2.7ubuntu17.1_amd64.deb ia32-libs

sudo cp ia32-libs/usr/lib32/libstdc++.so.5.0.7 /usr/lib32/

cd /usr/lib32

sudo ln -s libstdc++.so.5.0.7 libstdc++.so.5

This should get you going.
