Generating list of all RT CPAN dependencies

RT Developers

I responded to your message earlier from my email-client using the
“Followup” function in my client, but my response ended up un-connected
to this thread. Apparently responses must have the correct To-header for
the forum software to route responses correctly. Using the CC-header
does not seem to work.

My response ended up here:

I have created a ansible role for installing RT. The role performs a
fully automatic installation of RT for our purposes. The complete role
is not generic enough to distribute in full (Debian-specific), but the
role contains some ansible tasks which (somewhat hackishly) tries to
resolve RT dependencies. First by deducing suitable Debian packages, and
then be falling back to installing missing perl modules from CPAN.

Hopefully you can get some ideas on how to automate your installation
from this.
