Linux: perl -MCPAN -e shell 100%
Win32: ppm 80%
perl -MCPAN -e shell 20%
I use PPM on win32 boxes when the module is available. If there is a newer module on CPAN than PPM shows, do not install it! I've been bitten by this too many times, what happens is that there is probably some unsupported feature in the CPAN module and that's why activestate hasn't updated there PPM repository yet. Otherwise, if the module I want doesn't exist in the PPM repository, I'll use CPAN shell.
What time is it? It's Camel Time!
