postgresql83 missing dependency 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

Error: The following dependencies failed to build: readline

After installing "libranlib" it builds and installs fine.

Sorry about the messy build log, here it is again, in readable wikiformatted form:

/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

ranlib should have been installed as part of Xcode (like ar was); perhaps your Xcode install is incomplete?

Closing due to lack of response. I had no problem installing postgresql83 @8.3.7_0 on Tiger without libranlib installed. ranlib is in /usr/bin.
