perl - How can I generate call graphs for Perl modules and scripts?

Question

I have a bunch of Perl scripts and Perl modules given to me by someone. I have a driver program that tests all these scripts and modules. I want to generate a call graph and see the flow.

Is there something available for Perl for doing this?
I'd like something like pycallgraph (for python). I am running all this in AIX.

Simon Cozens在Perl.com上的Profiling Perl中告诉您如何做到这一点。他使用了Devel::DProf和GraphViz的组合。
