I think I fixed most of the errors. Mostly by including the missing modules and going through each error. There are two more things I have to do: 1. I have to replace "confess" keyword with "die", because it compalined "Cannot use bareword "confess" when "strict subs" is in use". Can i get the module that Confess is present. 2. My current test scripts use Test.pm file which is not supported in v5.004. Do I need to rewrite the tests again?
