build failure on OSX w/ universal (fat) ruby

[zenspider]

Looks like libxml2 and friends are not being built w/ multiple architectures and that's causing a failure.

Repro:

% gem i -i xxx nokogiri -V

I'm getting different failures from @tenderlove for some unknown reason, but we both have this problem in common.

my ruby is stock ruby on latest osx. latest xcode. latest rubygems.

The problem is that when we use the embedded libxml2, it doesn't get compiled as a universal binary even though system Ruby on OS X is a universal binary. This patch against the v1.6.2 tag seems to fix it:

diff --git a/ext/nokogiri/extconf.rb b/ext/nokogiri/extconf.rb

However, I can't seem to reproduce the issue against master.

It looks like 3c0137c fixes this, so I'm closing this ticket. Thanks!
