Actually, we've fixed this months ago:

  http://github.com/tenderlove/nokogiri/commit/602720e6

The problem is that MacRuby doesn't have a HAVE_RUBY_ENCODING_H
constant.  In Ruby 1.8, the correct thing is to include "st.h".  In 1.9,
we must include "ruby/st.h".  The way we determine which to use is by
looking for HAVE_RUBY_ENCODING_H.  HAVE_RUBY_ENCODING_H is defined in
1.9, but not in 1.8.

I'm happy to add an extra switch to the header file if there is
something special I can do for MacRuby.
