PPM - Perl Package Manager
from Active State
ppm is a graphical OR command-line package manager utility. Although it comes with your Active State installation, you may need to add a few repositories.
Active State Perl (for awhile) has had a GUI ppm, but if you know what you want, you can cut to the chase via the command line:
ppm install Package::Name

Target machine has no internet access. Now what?
Download the files on another machine, point ppm to the network location (or storage, whatever).
ah, but ppm doesn’t have a download facility.
DateTime, so had to download the following:
TimeDate-1.19-PPM510.tar.gz TimeDate-1.19-PPM56.tar.gz TimeDate-1.19-PPM58.tar.gz TimeDate.ppd
copy to a location available to target-machine, then execute
ppm install <path-to>\TimeDate.ppd
