Even if this reply may come a little late (I need some time to read the
thread and was a bit busy the last days):

I'm going to plunder on FreeBSD - there're some files maintained:
ports/MOVED, ports/UPDATING etc.

ports/MOVED is read by the ports-tools like portmaster, portupgrade etc.
It should be possible to create sth. similar (pkgsrc is using settings in
the makefiles, ok), e.g. that DEPENDS could be grouped:
DEPENDS+=       DEPENDS.fam

.include "../../xxx/fam-depends.mk"

...
in /etc/mk.conf:
fam={fam|gamin|libdev|...}
...

The dependencies may resolved like group options.
So pkg_rr could detect the change of a dependency and do

automatically.

Maybe you built it with pangocairo option, which requires glib which
requires libfam (e.g. gamin).
Sorry for that - I didn't find a way around.
