need help making local port on OSX

I would like to make a local build of libraw into my macports distribution. If anyone can help, I would appreciate it. The portfile is:

# -*- coding: utf-8; mode: tcl; tab-width: 4; indent-tabs-mode: nil; c-basic-offset: 4 -*- vim:fenc=utf-8:ft=tcl:et:sw=4:ts=4:sts=4
# $Id$
PortSystem 1.0
name LibRaw
version 0.13.0-Beta3
categories graphics
platforms darwin
maintainers wyatt \
description raw image decoding
long_description libraw is a library for raw image decoding
master_sites ${homepage}/data
checksums md5 1f8f6b032b07b0347b229fb03f1617b4

and when attempting to use it I get the following:

ejm$ sudo port install libraw
---> Fetching LibRaw
---> Verifying checksum(s) for LibRaw
---> Extracting LibRaw
---> Configuring LibRaw
---> Building LibRaw
Error: Target returned: shell command failed (see log for details)
Log for LibRaw is at: /opt/local/var/macports/logs/_Users_ejm_src_ports_graphics_libraw/main.log
Error: Status 1 encountered during processing.

Add the following line to your portfile:

use_parallel_build no

(Looks as if with the current makefile, when using parallel builds it's possible to want to link your executables before the library has beem built.)
