I am getting the following error while installing on windows with ruby v 2.0. I have installed DevKit for 64 bit. Temporarily enhancing PATH to include DevKit... Building native extensions. This could take a while...

I get the same error, I solved with the 32bit version, ruby+devkit

Same error. Any ideas for workaround without switching to 32bit version or Ruby? My CPU is indeed a x86-64 compatible CPU.
