Personally, I haven't really seen any issues installing Par::Packer on various builds of ActivePerl 5.12 & 5.14. However, it looks like you're trying to download the tarball from CPAN, uncompress it and manually trying to build and install the module. Since I have not tried that process myself on this module, I really can't offer any pointers on going that route.

Here's the steps that I would take to install Par::Packer after a fresh install of ActivePerl:

• Using PPM, install MinGW and dmake. (I typically use the GUI version of PPM, but I don't see why the line command version wouldn't work.)
• Install Par::Packer from CPAN by running the following from a command prompt: cpan install Par::Packer

That's pretty much it. If you're behind web proxy, you might need to configure the http_proxy setting for the CPAN module or add the http_proxy environment variable to the OS.

I believe that for some reason that a dependency or two failed to install for me in a few cases. When that happened, I installed those via PPM (if they were available from there) or via CPAN and then retried to install Par::Packer via CPAN.

Give the above steps a shot. If you run into any problems with that, come back and post what happened along with the error messages.
