Error installing Nokogiri in Ubuntu 10.10

Following Nokogiri Installation for Ubuntu I run below #nokogiri requirement in my terminal:

sudo apt-get install libxslt-dev libxml2-dev
sudo gem install nokogiri

Running “sudo gem install nokogiri” displays the following error:

Building native extensions.  This could take a while...
 ERROR:  Error installing nokogiri:
 ERROR: Failed to build gem native extension.
/usr/bin/ruby1.8 extconf.rb
 extconf.rb:5:in `require': no such file to load -- mkmf (LoadError)
 from extconf.rb:5
Gem files will remain installed in /var/lib/gems/1.8/gems/nokogiri-1.4.3.1 for inspection.
 Results logged to /var/lib/gems/1.8/gems/nokogiri-1.4.3.1/ext/nokogiri/gem_make.out

Was able to resolve the issue by installing ruby1.8-dev and reinstalling the nokogiri gem:

sudo apt-get install ruby1.8-dev 
sudo gem install nokogiri 

exist@exist:~$ sudo gem install nokogiri
