First things first, it is Apache::PAR, not Apache::Par. Perl is very much so case-sensitive! Next up, I checked and it looks like Apache::PAR is not part of the core distribution of ActiveState (at least not my version) and the module isn't listed on ActiveState's repository. It might be on one of the others, I'll leave that as an exercise for you to undertake.

That pretty much leaves installing it straight from CPAN. Before you attempt that, I strongly recommend that you take a look at the Tutorials, specifically the ones on modules.
