libxml-ruby gem requires libxml2 and other support libraries.

That will be the reason why is failing to install.

Are you using Ruby provided by RubyInstaller?

Gem author of libxml-ruby has provided in it's version 2.0 binaries for 
mingw32 platform, which will not trigger the gem compilation process 
using bundler.

Can you upgrade to libxml-ruby 2.0.x?
