postgresql83 missing dependensy on libranlib

[macports.org@…]

The package "postgresql83" fails to build unless "libranlib" is installed. Tail of the build log without "libranlib" installed:

/usr/bin/gcc-4.0 -DHAVE_CONFIG_H -I/opt/local/include -I. -I. -DRL_LIBRARY_VERSION='"6.0"' -O2 -DREADLINE_LIBRARY -c ./tilde.c rm -f libreadline.a ar cr libreadline.a readline.o vi_mode.o funmap.o keymaps.o parens.o search.o rltty.o complete.o bind.o isearch.o display.o signals.o util.o kill.o undo.o macro.o input.o callback.o terminal.o text.o nls.o misc.o compat.o xmalloc.o history.o histexpand.o histfile.o histsearch.o shell.o mbutil.o tilde.o ar: can't find or exec: ranlib (No such file or directory) ar: internal ranlib command failed make: * [libreadline.a] Error 1

Error: The following dependencies failed to build: readline Error: Status 1 encountered during processing.

After installing "libranlib" it builds and installs fine.
