Importing a single Perl script

[Edgar Fuß <ef%math.uni-bonn.de@localhost>]

These are probably trivial questions, but I want to get it right.

I just pkgsrc-ed a single Perl script (dhcpd-report).
Everything works, but I want to make sure I'm doing everything the way it's
intended in pkgsrc. So could someone in the know please comment on the Makefile
below and answer a few specific questions?

MASTER_SITES: I've also seen http://search.cpan.org/CPAN/authors/...
USE_LANGUAGES: I assume it's correct not to mention Perl here?
USE_TOOLS: Various other packages just add perl with a comment referring to
        pod2man. However, pkglint warns about this. Is it correct to add 
pod2man?
EXTRACT_SUFX/CMD: Is ${CP}ing the right way to do this?
Manyfing Perl documentation: Is there a more generic way other than calling
        pod2man explicitly?

Thanks for any comments.
