CPAN is your friend :) I've found these modules:

• Devel::DProf
  

  The Devel::DProf package is a Perl code profiler. This will collect information on the execution time of a Perl script and of the subs in that script. This information can be used to determine which subroutines are using the most time and which subroutines are being called most often. This information can also be used to create an execution graph of the script, showing subroutine relationships.

• Devel::Profiler
  

  This module implements a Perl profiler that outputs profiling data in a format compatible with dprofpp, Devel::DProf's profile analysis tool. It is meant to be a drop-in replacement for Devel::DProf.

• Devel::AutoProfiler by samtregar
  

  The profiler module is completely automatic in its basic mode. You simply "use" the module at the top of you main script. The module will then automatically instrument all subroutines in the code, profile each subroutine call during the execution of the script, and print out a report of usage.

There also some nodes here at the Monastery:

• Module dependency tool?
• robustly list any Perl code's module dependencies
• Check a script's module dependencies
• Generate UML from Perl code?
• MoDetails v0.2 by hacker
• Creating a Dependency Tree Using the Tree::DAG_Node Module and Postorder Transversal
• Any UML tool for Perl?
• Perl UML conventions
• UML for PERL?
