>Release:        FreeBSD 6.2, mostly
>Organization:
Filesystem and Storage Lab, Stony Brook University
>Environment:
FreeBSD with ports tree
>Description:
The "make package-recursive" target for ports will rebuild all tarballs for packages that are installed, even if the tarball exists in /usr/ports/packages.

When upgrading existing ports, or installing new ports with unbuilt dependencies, it is unnecessary to rebuild the existing tarballs.
>How-To-Repeat:
Run make package-recursive on any port with deep dependencies -- ports will rebuild every tarball dependancy, not just the ones that are unbuilt.
>Fix:
This patch, to /usr/ports/Mk/bsd.port.mk will add a target, "package-smart", which will build package tarballs recursively skipping those which exist already.
