Spell out your words, please. And did you try to look this error up?? zlib is already installed, but it's probably looking for the zlib-DEVEL package. Try "yum search zlib*", and install the zlib development package. Also, why are you specifically trying to install rails 3.1, rather than just typing in "gem install rails"???

And what version of CentOS are you using?
