[Opensvcdecoder-support] mac os build error

[Brett S. <bre...@gm...>]

Hello, any help with this would be greatly appreciated:

Using Mac OS 10.7.2 (also tried on Ubuntu, but had trouble installing SDL
there). I am interested in first using MPlayer to test this open svc
decoder on my svc streams, and if that goes well, in using the decoder in a
c++ project for my graduate work...

-clicked the main download button here:
http://sourceforge.net/projects/opensvcdecoder/
-downloaded and installed SDL
-typed ./configure --enable-svc, succeeded
-typed make

received the following error:
