Personally, I don't like wading through debugger output (maybe because I've done a great deal of it just recently).

Perhaps a better option for you, depending on your needs, is something like that mentioned in the following threads:

• What modules does my code require?
• Apply a source filter to all modules to be loaded?
• Which modules does somescript.pl use?
• Use of %INC ?

and etc.

(I played with that last one for a while today, in relation to various problems.)
