I encountered the same problem when I was installing Rails on Ubuntu but I was able to install zlib and then proceeded to installing Rails.

Here's what I did:

  1. Download and installed zlib from source.

    wget http://zlib.net/zlib-1.2.7.tar.gz
    tar -xvzf zlib-1.2.7.tar.gz
    cd zlib-1.2.7/
    sudo ./configure && sudo make && sudo make install

  2. "Register" zlib module before recompiling and reinstalling Ruby

    cd ruby-source-distro-path/ext/zlib

    sudo ruby extconf.rb

    sudo make && sudo make install
