Continuous integration is not only about the compiling, but also
running unit tests.

Yes, but you don't even need to do perl -c, since if your code doesn't
compile then your tests should obviously fail. You can have a test
that uses tools like Test::UseAllModules to make sure all the .pm
files in your application actually compiles.

There's a plugin for Perl's Test::Harness that supports JUnit output
which you can inject into Hudson. You can see all the reports and get
notification when one of the commit breaks your test suite. Pretty
