Ruby: cannot resolve dependencies for win32 package

I just installed win32-clibpoard for Ruby but it does not work because of a highly descriptive message RubyGem version error: win32-api(1.4.5 not >= 0).

Help needed.

C:> gem install win32-clipboard

You should uninstall the actual gem win32-api, just execute gem uninstall win-32-api and then proceed with:

1 Download the gem from http://rubyforge.org/frs/download.php/62628/win32-api-1.4.5-x86-mswin32-60.gem

2 And install it locally with: gem install win32-api-1.4.5-x86-mswin32-60.gem

3 and then try: gem install win32-clipboard
