in reply to do i need to have a better make - all perl-things fail

You need to install prerequisite modules. We've covered this previously.

Can't locate MozRepl/RemoteObject.pm

You don't have MozRepl::RemoteObject and other dependencies installed. Use cpan to install modules:

cpan WWW::Mechanize::Firefox

Or consult your OS package management system.

Repeating the same statements time after time isn't going to magically make you understand what you're trying to do and how to get it working. You have to read the advice people give you and the errors messages you receive.
