You have a good memory.
This was changed in revision 1.73 of bsd.pkg.mk:
date: 1998/04/22 14:22:46; author: agc; state: Exp; lines: +27 -33
Remove the old deprecated DEPENDS definition from bsd.pkg.mk.
Implement a new DEPENDS definition, which looks for an installed
package, building it if not present, and use it in preference to
LIB_DEPENDS. This should make the package collection more useful on
NetBSD ELF ports.
If you still have packages around from before April 1998, I think you'll
be running into more problems than simple DEPENDS syntax ones.
PS. The comment in the code of rev 1.73 explained it:
