Tech support for PerlEx sucks. It took them two weeks to get to a question I asked and then didn't provide a solution for it. The problem I had was related to a bug in both program and documentation, so I think they should have paid more attention to it; but the bug I was needing a fix for had been filed by other four months before and they hadn't yet gotten to it. Given this evidence of poor support I had to stop trying to use the product. (And PerlEx comes as closed-source binary, which also sucks)

If you want more attention then you may need to buy a support contract. You can also look at their bug-tracking system to see if your problem has been experienced by others.
