Answer 1

Hello,

Looks like hpricot gem you have installed lack binaries to support Ruby 1.9. All Gem that contains C extensions pre-compiled are linked against Ruby 1.8 or 1.9 binaries, and are not interchangeable.

A recommendation to point gem authors is build what is know as fat-binaries which provide support for both 1.8 and 1.9 versions of Ruby on Windows.

Alternatively, you can install Ruby using RubyInstaller binaries and compile the gem yourself using the Development Kit

Answer 2

Turns out that the hpricot_scan.so and fast_xs.so have the wrong file ending. They should be .dll and not .so
