title: Rails 3 - no such file to load -- openssl
body: <p>when running a Rails server, I get the following error:
  no such file to load -- openssl</p>
  
  <p>I try a solution I find online. I go to ~/.rvm/src/ruby-1.9.2-head/ext/openssl. I type : ruby extconf.rb, but I get the following:</p>
  
  <pre><code>=== OpenSSL for Ruby configurator ===
  === Checking for system dependent stuff... ===
  checking for t_open() in -lnsl... no
  checking for socket() in -lsocket... no
  checking for assert.h... yes
  === Checking for required stuff... ===
  checking for openssl/ssl.h... no
  === Checking for required stuff failed. ===
  Makefile wasn't created. Fix the errors above.
  </code></pre>
  
  <p>I cannot use make nor make install.</p>
