Greetings Monks,

I've been working on a small suite of programs lately, and I've recently come to the conclusion that I need to write an installer for them. The reason: The vast majority of people using and installing the programs will be idiots unable to deal with simple things such as installing modules or configuring each script with the correct path to Perl (Or: Be subject of moronic administrators at their server and unable to do those things in a timely fassion).

On this subject, I've found a few things I wasn't sure about, so I decided to ask.

1) What's the fastest/most efficient (without wasting memory) way to check if a module is installed?

2) What happens when a program tries to use 'CPAN' but no one has configured it?

3) Is there any way to determine the path to sendmail? Or is there a common default path?

Thats all for now, thanks if you bothered to read the whole thing :)
