Yes, realized what was happening after my post, but did not
know how to delete my post. The above is not related to my problem,
actually works fine.

That is exactly what was happening.

nokogiri.so is indeed in 

/usr/lib/ruby/gems/1.8/gems/nokogiri-1.4.2/lib/nokogiri

gcc is installed, and I have been building other libraries.

So this is error again from irb:

irb(main):002:0> require 'nokogiri'
LoadError: No such file or directory -
/usr/lib/ruby/gems/1.8/gems/nokogiri-1.4.2/lib/nokogiri/nokogiri.so
from /usr/lib/ruby/gems/1.8/gems/nokogiri-1.4.2/lib/nokogiri/nokogiri.so
from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'
from (irb):2

I have even tried pointing:

RUBYLIB=/usr/lib/ruby/gems/1.8/gems/nokogiri-1.4.2/lib/nokogiri

...with no result.

The strange part is the "No such file or directory". It seems that if
the library was failing to load it would give a different message. But
since the library is indeed there, it is interesting.

I just went through and added group 'Users' to libsml2 and libxslt, libexslt,
in case that was a problem. I noticed there was not a group assigned in 
the libraries I installed.

Actually, I am wondering at this point if it is the copies of the above 
libraries I am building against that could be the problem. However, I do
believe it is the libraries at xmlsoft.org I built against.

Cheers,

   Jet
