title: I can't install sqlite3 gem for Ubuntu 10
body: <p>I use apt-get to install sqlite3 in my VPS which is running Ubuntu 10. I can run sqlite3 with no problem. But when I try to use gem install sqlite3, I got this error:</p>
  <pre><code>root@makserver:/# gem install sqlite3
  Building native extensions.  This could take a while...
  ERROR:  Error installing sqlite3:
      ERROR: Failed to build gem native extension.
  
          /usr/local/bin/ruby extconf.rb
  checking for sqlite3.h... no
  sqlite3.h is missing. Try 'port install sqlite3 +universal'
  or 'yum install sqlite3-devel' and check your shared library search path (the
  location where your sqlite3 shared library is located).
  *** extconf.rb failed ***
  Could not create Makefile due to some reason, probably lack of
  necessary libraries and/or headers.  Check the mkmf.log file for more
  details.  You may need configuration options.
