It's clearly telling you that you don't have zlib:

cannot load such file -- zlib

You haven't provided any details to what system you are running.

sudo apt-get install zlib1g-dev

or

sudo yum install zlib-devel

for red hat/centos/ubuntu systems. You'll then have to reinstall ruby. You may have some other dependencies and might need libyaml-dev or openssl.
