[Mimedefang] graphdefang requirements

[cc]

Hi,

I don't know if this is OT here, but since
this came with MIMEDefang, I figure I'd
ask and see.

I read the readme file and am quite 'confused''
about a few things, mainly about the perl
modules required.

I went to CPAN and couldn't find:

Date::Parse and Date::Format

There are quite a lot of Date-Format
modules, but I'm not sure which one I need.

Btw, this is a recurring issue I've
had with other perl packages.  In
these situations, what exactly do I
do?  Do I just grab whatever module
or do I grab and install all related
perl modules(something I'm not too keen on)?

Any information appreciated.

Thanks.
