Error installing cucumber: - ERROR: Failed to build gem native extension

Hello All,

I am installing cucumber on my windows XP machine by using the command
“gem install cucumber -v 0.10.0”

But gets the following error :

Temporarily enhancing PATH to include DevKit…
Building native extensions. This could take a while…
ERROR: Error installing cucumber:
