Ruby Gem Curb version 0.8.5 - Wont install - Windows 7 Setup with RubeMine 6.0.1

Question

I get the following errors, basically trying to get curb to go but it wont. Here is a snapshot of my terminal:

gem install curb -- -with-curl-lib=c:/curl-7.33.0/lib
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing curb:

options to extconf.
