The problem with this is, that a lot of ports hardcode
grandparent-libs. This is not a FreeBSD problem, this is a libtool (at
least 1.x) problem and a pkg-config problem (adding grandparent-libs
even if they are not necessary). So with this switch, you can not
lookup potential candidates for an upgrade, by looking at the
Because of the libtool/pkg-config problem all childs of a
"problematic" lib will contain a reference to the lib, even if the
particular lib is just a dependency of a lib which the current port
uses. To make this description more explicit: if your port uses
libGRAPH (I made upt this name) and libGRAPH is linked to libjpeg and
libpng via libtool (at least 1.x), but your port is not directly using
symbols from libjpeg or libpng, the binaries of your port will have
libpng *and* libjpeg hardcoded.
See /usr/ports/Tools/scripts/explicit_lib_depends.sh for a script
which tells you which libs are hardcoded in the files (if they are in
bin/ or lib/) of your (installed) port. Feel free to improve the
script, I didn't touch it since 3 years because the software in the
ports tree was not in a state where it made sense to finish the "NOT
YET" part or extend the scope of files to analyze.
