You certainly don't have to be an expert in Perl, but you will need to (learn to) diagnose why the test suite of a distribution hangs on your machine, and how to blacklist those distributions.

If you want to provide more help, you will have to have at least some knowledge about your platform, and about the likely expectations of the programmer that went wrong on your platform. To find these faulty assumptions, a bit of Perl knowledge is needed.

thank you for your help
