Perl::Metrics::Simple provides just enough methods to run static analysis of one or many Perl files and obtain a few metrics: packages, subroutines, lines of code, and an approximation of cyclomatic (mccabe) complexity for the subroutines and the "main" portion of the code. Perl::Metrics::Simple is far simpler than Perl::Metrics. Installs a script called countperl. WWW: http://search.cpan.org/dist/Perl-Metrics-Simple/
