Windows-pr requires win32-api (>= 1.2.1, runtime)

The problem is that gem can only find win32-api v 1.2.0

$ gem install win32-api
Building native extensions. This could take a while…
Successfully installed win32-api-1.2.0

Sooo… where/how do I get 1.2.1?

Sooo… where/how do I get 1.2.1?

I got the same problem. Appears that installing it via:
http://rubyforge.org/frs/?group_id=85&release_id=30021 [download the
.gem file, install it] is currently the only way to get > 1.2.0 [and
install win32-process, etc.]
Thanks!
