I suggest taking a look at section 5.7.1 of the porter's handbook, which
describes the format for LIB_DEPENDS entries. You almost got it right on
the second try -- by taking a quick glance at
/usr/ports/Mk/bsd.gnome.mk, you can see this in line 281:

  gtk20_LIB_DEPENDS=      gtk-x11-2.0.0:${PORTSDIR}/x11-toolkits/gtk20

By the way, taking a look at the comments in the beginning of
bsd.gnome.mk is also a good idea, as it shows you can use something like

  USE_GNOME=gtk20

and be done with it.
