Problem when installing dbsize of PG 8.0-beta1

I installed PG 8.0 Beta 1 in my machine. Everything seemed ok... The
problem occurred when I tried to install the programs in contrib
directory...
I commented out dbsize from the Makefile... And everything installed
successfully... Following is compiling output of dbsize... Am I doing
anything wrong or GETDATABASEPATH is broken?

gcc -O2
-fno-strict-aliasing
-Wall
-Wmissing-prototypes
-Wmissing-declarations
-fpic
-I.
-I../../src/include
-D_GNU_SOURCE
-c
-o dbsize.o dbsize.c

dbsize.c: In function`database_size': dbsize.c:58: error: too few
arguments to function`GetDatabasePath' gmake: *** [dbsize.o] Error 1

Current configuration of PG:

pg_config --configure
--prefix=/usr/local/postgresql-8.0
--with-java
--with-perl
--enable-nls
--with-openssl
--with-tcl
--with-pgport=5435
--enable-thread-safety
