after pkg-config -> pkgconf update lots of packages show missing dependency on devel/pkg-config

[Anton Shterenlikht]

I did portmaster -o devel/pkgconf devel/pkg-config
as advised. Now doing "portmaster --check-depends"
returns 235 ports with
"missing dependency: devel/pkg-config".
I thought the "-o" portmaster option is specifically
to update the dependencies list. Am I wrong?
Or is this not possible in this particular case?

Anyway, I presume this is a benign warning, and
none of my 235 ports need to be rebuid, right?

Thanks
Anton
