Hi and sorry for the late reply. (I had some cookie-related trouble with logging in. Don't ask.)
Perhaps it wasn't there at the beginning of December, but now, there is PAR-Packer-588 in Randy Kobes' repository. You can also install the PAR-Packer-0.970-MSWin32.....-5.8.8.par on CPAN in my author directory (SMUELLER) alongside the non-binary PAR/PAR::Packer releases. You can install it by using CPAN.pm to install PAR::Packer. It should automatically fetch that .par file for you if you don't have a compiler at hand.
Hope this helps!
