Nokogiri + Libxml2 woes

1. Installing the nokogiri gem.

Without libxml2 installed, nokogiri gives you an error asking you to run 'yum install libxml2-devel'

My slice is on Ubuntu, so I have to run 'aptitude install libxml2-dev'. Then nokogiri asks me to install libxslt, so I run 'aptitude install libxslt'.

Nokogiri installs and all is well with the world, until...

2. Then I get this when trying to run my app: http://github.com/tenderlove/mechanize/issues#issue/9

So I apply the patch. No luck. The comments say I need a newer version of libxml2 than aptitude will give me.

3. Following these instructions, I install libxml2 from source after removing it with aptitude. No luck. Now I get this:

  libexslt.so.0: cannot open shared object file: No such file or directory - /usr/lib/ruby/gems/1.8/gems/nokogiri-1.4.1/lib/nokogiri/nokogiri.so

No fair. libexslt.so.0 is in /usr/local/lib.
