I believe Ruby 1.9.1 is not compatible with Rails 3 (see the Rails
Guide, Getting Started). You should upgrade to 1.9.2 I think. Of
course this may or may not be the cause of your particular problem.

If you are using RVM:
rvm package install readline
rvm remove 1.9.1
rvm install 1.9.1 -C --with-readline-dir=$HOME/.rvm/usr

Otherwise try:

sudo apt-get install build-essential
sudo apt-get install bison byacc gperf
sudo apt-get install zlib1g-dev
sudo apt-get install libreadline5 libreadline5-dev
sudo apt-get install libncurses5 libncurses5-dev temcap-compat
sudo apt-get install libssl-dev

Hope that helps.

ruby 1.9.1 is not supported use 1.9.2
