Oh, I wasted LOTS of time doing this. :-) I think, had I known how to do it, it wouldn't have taken much longer than your 2 minutes. The two 20 minute waits (and I didn't time them accurately - that's an estimate) were for the installation of the C compiler and ?make utility. Without that the computer time would have been much shorter. But even the 40 minutes for that was only a small part of the time I wasted not knowing what to do and googling frenetically. That's why I thought it might be worth putting up the OP in case someone found themselves in the same boat.
I'm interested to see you using wget instead of the two tools I'd heard of previously. Is this documented anywhere? Especially, is there any documentation on which to use and when? As I stated in the OP, the only ones I've ever tried are PPM and the CPAN shell (I've also used Debian's apt-get on the Pi).
