Subject: rvm / gem install not working (zlib issue) on ubuntu

Hi

  gem install is not working under rvm on my ubuntu 10.04 system. The
error is related to zlib.

Note I have followed instructions on stackoverflow related to this and
still come up short.

$ gem install redcar

ERROR:  Loading command: install (LoadError)
    cannot load such file -- zlib
ERROR:  While executing gem ... (NameError)
    uninitialized constant Gem::Commands::InstallCommand

Here is output for zlib on my system

steve@mithril:/shared/hbase$ dpkg -s zlib*
Package `zlib*' is not installed and no info is available.
Use dpkg --info (= dpkg-deb --info) to examine archive files,
and dpkg --contents (= dpkg-deb --contents) to list their contents.

I am posting here instead of Stackoverflow because posting messages
stopped   working for me on SOF, both on FF and in Chrome

Hopefully here this error will be familiar to many and can be answered
