The question about whether or not the module can be used without the prereqs is probably best answered by the author. However, the fact that, for example, Crypt::DES is listed as a prerequisite in Makefile.PL, and also that this module is use()d in some of the associated Net::SNMP::* modules, makes one suspect that these prerequisites are considered mandatory.

As for installing this package and its prerequisites on other boxes, there's a few options, depending on whether or not they have network access.

• if unrestricted network access is available, you could add a repository within the ppm shell that contains these packages; one such repository is the uwinnipeg one.
• if the network access is restricted, you could set up a local package repository, as described in A guide to installing modules for Win32.
• if no network access is available, you can make up a zipped file containing the ppd and tar.gz files making up the ppm distribution; there's examples on ActiveState's site for how to do this.
