Trying to build mplayer on Mac OS X 10.6 (Snow Leopard)

All,

I'm trying to build mplayer under Snow Leopard with no success (yet).   
My initial attempt failed during 'configure' with the following:

Check "configure.log" if you do not understand why it failed.
*** Error code 1

Stop.

A quick Google turned up the answer (http://lists.mplayerhq.hu/pipermail/mplayer-users/2009-September/077726.html 
) -- you have to pass '-target=x86_64-Darwin' to gcc to correctly set  
the CPU type for the mplayer configure script.  When I do this on the  
command line from within the work/MPlayer directory and run  
'configure' it goes to completion.  I can't figure out how to do this  
from within the pkgsrc Makefile, though.  Setting 'CFLAGS+=- 
target=x86_64-Darwin' or 'CFLAGS=-target=x86_64-Darwin' in the  
Makefile doesn't seem to work.  I'm sure this is straightforward but I  
can't seem to figure it out!

Thanks for any help,

Steve
