if it can be used for our Perl code-base

Yes it can

lots of nice stats for them to look at

The metrics, or visualizations of the metrics, are useful from a QA and general project management point of view.

We (Java/C/C++ environment) use it in combination with Maven (the build tool) and Sonar (code quality). Tools are integrated into JIRA (for project tracking) via plugins. One centralized environment:) Needless to say it saves a lot of time compared to glueing the different tools together with scripts/cron jobs.
