Well, I will own up to that. I was very frustrated. Perl does so many things so well that I get impatient when it doesn't do something seemingly ordinary by itself for me by magic. ;-)
I really liked Cava Packager; I was surprised and disappointed that it didn't bundle things as neatly as I thought it should have. pp looked pretty good, and lots of people rave about PAR; I was frustrated by what I thought was a fairly big stumbling block.
Perhaps what I really needed was to step back and look at the problem differently—and a lot of the posts in this thread suggest different approaches that I will certainly try.
+1 for the Perl community, anyhow.
