Sorry, I guess I wasn't clear. The fix I found, which seems to be for exactly the problem I am experiencing, is not working for me - Devel::Declare install still fails with the same error. I guess I could reopen the ticket or something, but I don't want to waste the developer's time if its something wrong with my setup, or something obvious I'm doing wrong which seems likely given my lack of knowledge. I guess I'm looking for suggestions of other things to try. I don't understand how these modules work well enough to proceed on my own.
