Generally, Perl modules map to MacPorts port names by case-squashing, 
replacement of :: with - and prefixing with 'p5-' or p5.##- where ## 
denotes the specific Perl minor version (without patchlevel.) The p5-* 
ports are wrappers with variants for the available Perl versions and 
dependencies on the versioned ports.

There are ports for many "pure Perl" modules. It is generally unwise to 
use CPAN (either via the cpan script or 'perl -MCPAN -e <command>') to 
install modules that exist as ports, particularly to fix dependencies in 
MacPorts-originated software.
