sqlite3-ruby install error on Ubuntu

I have the following error during sqlite3-ruby install:

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

Ubuntu 10.04

If you are a ruby programmer, then using rbenv or rvm is a "best practice" - which will keep the OS ruby stuff away from your ruby stuff, including gems.
The first few chapters of this free book explains: http://ruby.railstutorial.org/chapters/beginning

I've setup Ruby-on-Rails on Ubuntu before - here's a guide: http://blog.jdpfu.com/2012/07/18/rub...n-ubuntu-12-04 Things may have changed slightly since then.

10.04 is nearing EOL. Desktop 10.04 supported ended about a yr ago. The Ruby-on-Rails guys are hyper-new with their coding - almost to the point of abuse, IMHO. That means it may not be possible to run newer gems on 4 yr old released versions of Ubuntu.
