Why are you using such an old version of libxml-ruby?  1.1.3 (the last tag in the 1.1 series) has a glaringly obvious bug with that top-level method_missing:

$ ruby -e 'def method_missing(*) p :called end; "".missing'
:called

I doubt 1.1.4 is any different.  Newer versions don't seem to have this extconf.rb bug.

Why aren't you using nokogiri?
