mailcatcher install problem

Hi - I am trying to install mailcatcher on Win 7 ruby 2.0.0p451
(2014-02-24) [x64-mingw32]. I have installed DevKit and am getting the
following when I do a gem install mailcatcher:

C:\rails_projects\store4>gem install mailcatcher
Temporarily enhancing PATH to include DevKit...
Building native extensions. This could take a while...
ERROR: Error installing mailcatcher:

Any help appreciated.


Use 32 bit versions of Ruby and DevKit.
