mod_perl2 port misses existing BSD::Resource dependency

[snowcrash+freebsd]

hi,

i've fbsd 62Rp7 installed, with perl 588 & mod_perl2 installed from ports.

perl modules are installed by CPAN, *not* using ports (p5-*).

i've successfully installed "BSD::Resource" -- a dependency of
mod_perl2 -- via CPAN,

	module_info BSD::Resource
		Name:        BSD::Resource
		Version:     1.28
		Directory:   /usr/local/lib/perl5/site_perl/5.8.8/mach
		File:        /usr/local/lib/perl5/site_perl/5.8.8/mach/BSD/Resource.pm
		Core module: no

despite BSD::Resource being installed/available, every time I do the
'update ports' mambo,

	portsnap fetch update
	pkgdb --autofix --fix-lost
	pkgdb -F
	portupgrade              --verbose --recursive --upward-recursive --all

i'm faced with a "stale dependency" warning,

	...
	--->  Checking the package registry database
	Stale dependency: mod_perl2-2.0.3_2,3 -> p5-BSD-Resource-1.28
(devel/p5-BSD-Resource):
	Skipped. (running in non-interactive mode; specify -i to ask)
	--->  Checking the package registry database
	Stale dependency: mod_perl2-2.0.3_2,3 -> p5-BSD-Resource-1.28
(devel/p5-BSD-Resource):
	Install stale dependency? ([y]es/[n]o/[a]ll) [yes] no
	New dependency? (? to help):
	Delete this? ([y]es/[n]o/[a]ll) [yes] yes
	Deleted.
	...

which I delete.  apparetnly, not persistently ... as it reappears @
the next port update.

how do i "convince" my port system to stop whining about the stale
dependency, or -- better yet -- recognize the existing CPAN module?

although i'm /hoping/ it's something in/with ports-mgmt, i /suspect/
it needs to be addressed in the port itself.

thanks!
