There's no way to do it fully automatically, but porters try to do this
by hand, by incrementing PORTREVISION for the dependent ports.  Once
that is done, portupgrade will pick it up automatically.  However,
porters will sometimes miss subtle dependencies, especially optional
ones.  

In this case, I don't see a direct dependency of inkscape on atkmm, so I
don't know how it should have been marked.  In any case, inkscape was
updated shortly after atkmm, so if you upgraded everything more
recently, it looks like you should have gotten inkscape rebuilt after
the atkmm change.
