I agree with the people suggesting using some kind of packaging tool.

I've had good luck with PAR in the past, (back before PAR and PAR::Packer split). I don't know how well it works these days, I haven't used it in a while.

After a lot of testing of PAR, perl2exe and Perlapp, I wound up using ActiveState's perlapp to create executables. It works well, and I've been very happy with it. It costs a couple hundred dollars, but with the cost of time it's saved me, it's been a very good buy.

I can't comment on Cava Packager. I haven't tried it.
