Only when you're adding packages locally. Here's what happens when you build 
packages of gmake & dependencies with your bpm-patch and then try to pkg_add 
-r them:

[lofi at kdeprison5]:1:/usr/ports > env 
PACKAGESITE=http://people.freebsd.org/~lofi/reduced-dep-packages/Latest/ sudo 
pkg_add -r gmake
Fetching 
http://people.freebsd.org/~lofi/reduced-dep-packages/Latest/gmake.tbz... 
Done.
Fetching 
http://people.freebsd.org/~lofi/reduced-dep-packages/All/gettext-0.14.1.tbz... 
Done.
pkg_add: could not find package libiconv-1.9.2_1 !
pkg_add: pkg_add of dependency 'gettext-0.14.1' failed!
[lofi at kdeprison5]:1:/usr/ports >

(you can make a crosscheck with packages built with the current bsd.port.mk by 
using http://people.freebsd.org/~lofi/standard-packages/Latest/ as 
PACKAGESITE).

Now I'm not saying that this isn't a bug - I'm just maintaining that there's 
more work involved in this than just patching bsd.port.mk.
