mplayer doesn't build for me under Leopard on MacBook Pro

[Lloyd Zusman]

I have recently upgraded to Leopard, XCode 3.0, and Darwin Ports 1.5.0 on
my MacBook Pro.

I am trying to install mplayer, but the build goes for a while and then
finally fails with this error (some long lines manually broken in order
to get this posted via Gmane):

.  Error: Target org.macports.build returned: shell command

.  make: *** [libavcodec/libavcodec.a] Error 2

.  Error: Status 1 encountered during processing.

Based on my googling and looking elsewhere, I think this is related to
the choice of C compiler that is used.  Here are the results of 
"cc --version":

.  i686-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1 (Apple Inc. build 5465)
.  Copyright (C) 2005 Free Software Foundation, Inc.

Does anyone have any ideas as to what I can do to get mplayer to build
under my configuration?

Thanks in advance.
