The good news is that there is nothing particularly complex about your module's composition that would prevent it from being installed the conventional way on ActivePerl using the standard CPAN tools (cpan, or cpanm for example). PPM support is most useful for modules that require difficult compilation. Your users have the alternative of just using the same install technique that non-ActiveState users employ.

If you think that Community Edition ActivePerl users might comprise a significant portion of your module's user base, you might consider adding an INSTALL file to the distribution that discusses ActivePerl installation options, or add a blurb to the README.
