So then you do "cpan Net::Twitter".
The dependency hell that follows results in 49 tar files downloaded, 91 packages installed, and 10,403 lines of compiler and installer output.
For 6 packets.
(Oh, and then it doesn't work anyway, because something called "Moose" fails to install with an "unknown error" -- which apparently really means "unsatisfied dependencies"! So it is a mystery how many packages it would have actually installed.)
