CPAN newbie question - tries to download perl 5.8.0?

[Jim Correia]

I've never used CPAN before - I've gotten by with the stock modules 
since I don't do too much perl hacking. But now I've got a script from 
a third party that needs some modules, so I figured I'd use CPAN to go 
get them.

So I fired up the cpan shell, answered all the initial questions (with 
the default answers). It suggested that I upgrade Bundle::libnet, so I 
took its advice and did so. As I was watching what it was doing, it 
started downloading perl 5.8.0

What is the story with this? I just wanted a teensy weensy little 
module. I didn't want to upgrade my whole perl installation.

How do I just go and grab say HTML::Parser (or whatever) starting from 
an unconfigured CPAN without running into this problem?

Thanks,
Jim
