Unfortunately, this isn't sufficient because a non-trivial number of ports dlopen() libraries rather than directly linking against them.

A third approach is to more carefully recurse through the dependency tree: Given A depends on B depends on C, B only needs bumping if it LIB_DEPENDS on A and C only needs bumping if it LIB_DEPENDS on B and B was bumped. In this specific case, p5-RT-* depends on www/rt38 depends on graphics/p5-GD depends on graphics/gd depends on graphics/jpeg. When jpeg is bumped, gd needs to be bumped because it LIB_DEPENDS on jpeg. p5-GD then needs to be bumped because it LIB_DEPENDS on gd. rt38 does not need to be bumped because it has no LIB_DEPENDS on p5-GD. p5-RT-* does not need to be bumped because rt38 is not bumped. This is slighly more complex than cd /usr/ports && \ for i in */*; do [ -d "$i" ] && cd "$i" && make all-depends-list ; done | \ grep jpeg because you need to actually follow the dependency tree, but is not impractical. The only issues I can see with this approach are: 1) Mapping the shared library reported by 'make lib-depends' back to the port than installs it. 2) You are relying on LIB_DEPENDS being correct: In my general example above, if A is missing a LIB_DEPENDS on C, this may not be detected in the build process because of the implicit dependency on C via B. No sample script because I'm not sure of the correct approach to 1) off the top of my head. -- Peter Jeremy
