gem install sqlite3-ruby

When I try install sqlite3-ruby, I get

# gem install sqlite3-ruby
Building native extensions.  This could take a while...
ERROR:  Error installing sqlite3-ruby:

It looks like you need to update your sqlite3 version. Not any gem, but the actual sqlite3 package. Use your distribution's package manager to upgrade to a version of sqlite3 >= 3.6.16+, or compile it from source (obtainable here)
