libpq (Postgres 7.2.1) + MacOS X 10.1.5 problem

Here's my simple program:

#include 
#include 

int main() {       int i, j;       PGconn *dbconn;       PGresult *results;
       dbconn = PQconnectdb( 	"hostaddr=AN_IP_ADDR user=USERNAME dbname=SOMEDB" );
       results = PQexec( dbconn, "select * from account" );
       for( i = 0; i < PQntuples( results ); i++ ) {               printf( "Row #%i\n", i );
               for( j = 0; j < PQnfields( results ); j++ ) {                       printf( "    Field: %16s / Value: %s\n",			PQfname( results, j ), PQgetvalue( re			sults, i, j ) 		);               }       }
       PQfinish( dbconn );       return( 0 );
}

I'm trying to compile a simple program using libpq and initially get
the following linker error:

-g -Wall -I/usr/local/pgsql/include -L/usr/local/pgsql/lib -lpq test.c
-o test
/usr/bin/ld: table of contents for archive:
/usr/local/pgsql/lib/libpq.a is out of date; rerun ranlib(1) (can't
load from it)
make: *** [all] Error 1

After running ranlib on libpq.a, I get the following:

gcc -g -Wall -I/usr/local/pgsql/include -L/usr/local/pgsql/lib -lpq
test.c -o test
/usr/bin/ld: Undefined symbols:
_PQconnectdb
_PQexec
_PQfinish
_PQfname
_PQgetvalue
_PQnfields
_PQntuples
make: *** [all] Error 1

Any ideas?
