It has been my expereince that if the module has been ported successfully to a given release of Active State it will show up in the PPM repository. I have also found in the past that for some modules I really cared about that AS lagged significantly behind on updating their pacakges in the repository. I discovered that trying to build packages that were lacking was often a major pain or impossible with their set up 8^(. Buried in their webpges they do have a list of what modules have been ported to which OS's but that does not always match with what they make available. This lag on their part led me to switch to Strawberry Perl as it seemed to have no problem building packages AS would not. I really like AS perl but have found Strawberry to be a very adequate replacement thus far.

I also imagine that the senior brothers and sisters here will have more specific and enlightening info than i have provided.

I hope this has helped a bit. Good Luck
