portmaster -w -r (pcre & icu): how to avoid redundant rebuilding?

[Thomas Mueller]

I see in the UPDATING file that I need to rebuild all ports that depend on pcre and icu:

portmaster -w -r pcre
and
portmaster -w -r icu
(I don't need -f ?)

How do I do this without rebuilding the same ports twice?

I am on pkgng, so I can use
pkg info -r icu
and same for pcre to list ports depending on icu and pcre (long lists).

I just updated, from source, to:
