Mapping Perl module names to corresponding FreeBSD port names

[Ronald F. Guilmette]

I am, at long last, moving my main system over onto a new drive where
I have just installed a fresh copy of 9.1-RELEASE, and where I have
built and installed essentially all of the ports I had on my old
(8.3-RELEASE) system... at least the ones that I am actually still
actively using.

A problem arises however in the case of the various p5-* (Perl) ports
that I have installed on my old 8.3 system.  How can I know which of
these I really need to install on my new 9.1 system, you know, in order
to make sure that all of my existing/old Perl scripts will continue to
function?

pkg_info says that I currently have 84 different p5-* ports installed
on my old 8.3 system.  The list of these is attached below.  (I suspect
that many/most of these I installed temporarily, just for some one-off
task, and that I no longer need to have them installed, e.g. on my new
system.)

I keep all of my personal scripts and compiled programs in a directory I
call /usr/local/rfg/bin.  I have gone into that directory and done:

	grep '^use ' | sort -u

in order to find all the the Perl module names that my various personal
Perl scripts are using.  The result is the following (which has been
trimmed a bit to remove irrelevant fluff):

use CGI::Lite;
use Cwd;
use Email::MIME;
use Encode;
use HTML::TreeBuilder;
use IO::Handle;
use LWP::Simple;
use List::Util qw(min max);
use Net::CIDR::Lite;
use Net::DNS;
use Time::localtime;
use URI::Escape;

So basically, on my new system, I need to install all of the p5-* FreeBSD
ports that correspond to the above set of Perl modules.  In order to
do this, I need to somehow derive the corresponding FreeBSD p5-* port
names from the Perl module names listed above.

In some cases, the mapping is both straightforward and obvious, e.g.:

	CGI::Lite	=>	p5-CGI-Lite
	Email::MIME	=>	p5-Email-MIME
	Net::DNS	=>	p5-Net-DNS

however in many other cases the correct mapping is not immediately obvious.

So, I need to ask:  Is there some simple automated way to map each of the
above Perl module names into a corresponding FreeBSD p5-* port name?
If not, is there a map published somewhere that I could just refer to in
order to find the name of the specific FreeBSD port that corresponds to
any given (CPAN-published) Perl module?
