If your module is available in Activestate PPM Repository, then the command `ppm install Net::RawIP` would install, else you have to invoke the cpan shell on command prompt by typing cpan and then fire `install Net::RawIP`. Alternatively you can download the zip file of the required module from http://ppm.activestate.com/PPMPackages/zips/ and install directly from the ppd file present in the zip using the ppm utility (See the links above)
