http://ppm.activestate.com/PPMPackages/zips/6xx-builds-only/Clone.zip seems to have the stuff to install on Windows... but no makefile.
I think all PPM does is copy these files to the right place, so maybe you can download the zip file and do the same thing my (working) PPM 2 did:
C:\>ppm
PPM interactive shell (2.1.5) - type 'help' for available commands.
PPM> install Clone
Install package 'Clone?' (y/N): y
Installing package 'Clone'...

Note: I've never actually tried this.
