I want to use octopress. so i view the "how to" in this website http://octopress.org/docs/setup/ All is successful until type "gem install bundler" in bash-shell The output likes the below:

[root@litian octopress]# gem install bundler
ERROR:  Loading command: install (LoadError)
    no such file to load -- zlib
ERROR:  While executing gem ... (NameError)
    uninitialized constant Gem::Commands::InstallCommand

I search on the web, and find that may be zlib1g and zlib1g-dev are short But when i use yum search zlib1g, the result is no match

i also find this Installing Rails Path on Ubuntu with RVM so i type 

rvm pkg install zlib

the output is

Fetching zlib-1.2.5.tar.gz to /usr/local/rvm/archives

remove your current ruby from rvm like rvm remove 1.9.3. install zlib sudo yum install zlib-devel and reinstall ruby like rvm install 1.9.3 then gem in bundler
