I wanted Libxml2 wrapped in a Ruby gem. So, I ran 

sudo gem install libxml-ruby

…and watched the software fail to build. Darn OS X not “just being Linux”. After complaining to Christoffer, I was kindly pointed to a MacPort: 

sudo port install rb-libxml2

OK, that worked. But I don’t want to use DarwinPorts/MacPorts for my Rubygems, the gems change far too often for that. What I wound up doing was reinstall my gem (sudo gem install libxml-ruby), and then copy the libxml.bundle to its folder:


# cp /usr/local/lib/ruby/gems/1.8/gems/xml/libxml.bundle \
/usr/local/lib/ruby/gems/1.8/gems/libxml-ruby-0.3.8/ext/xml/

Also, go into the file 

/usr/local/lib/ruby/gems/1.8/gems/libxml-ruby-0.3.8/ext/xml/libxml.rb

and change the required file’s name from xml/libxml_so to xml/libxml.bundle.

This was enough to make the thing work!

Moral: The right way to fix this would be to enhance the Makefile of the libxml-ruby gem to teach it about the OS X environment, but: not me, not today. This little tip is what I can do today. Ciao.
