problem with configure and PKG_CHECK_MODULES

[Dave Tyson <dtyson%anduin.org.uk@localhost>]

I've started to try and package up motion (a video camera monitoring package) 
and have run into a problem with the configure phase bombing out when it hits 
a line with a PKG_CHECK_MODULES statement. I have had a few tries at various 
kludges, but nothing seems to be working and I am wondering if its some 
linuxism which is tripping me up. This is under NetBSD 7.1/amd64.

My Makefile (first attempt!) looks like:

# $NetBSD$
#
DISTNAME=          motion-release-3.4.1
CATEGORIES=       security
MASTER_SITES=   -https://github.com/Motion 
Project/motion/archive/release-3.4.1.tar.gz
MAINTAINER=       pkgsrc-users%NetBSD.org@localhost
HOMEPAGE=        http://lavrsen.dk/foswiki/bin/view/Motion/WebHome
COMMENT=         Motion detecting video camera package

GNU_CONFIGURE=  yes
USE_TOOLS+=     autoconf pkg-config

pre-configure:
                cd $(WRKSRC) && autoconf

.include "../../graphics/jpeg/buildlink3.mk"
.include "../../multimedia/ffmpeg1/buildlink3.mk"
.include "../../mk/bsd.pkg.mk"

Looking at the generated Configure file its tripping up on the
PKG_CHECK_MODULES line:

....
if test "x$with_ffmpeg" != "xno"; then :
  
       if test "x$with_ffmpeg" != "xyes"; then :
  
              PKG_CONFIG_PATH=${with_ffmpeg}/lib/pkgconfig:$PKG_CONFIG_PATH
              export PKG_CONFIG_PATH
  
fi  
        PKG_CHECK_MODULES(FFMPEG, libavutil libavformat libavcodec libswscale, 
HAVE_FFMPEG=yes)
  
fi  
...

Any suggestions on what I am missing to fix this problem?

Cheers,
Dave
