libsdl: basic test case fails on osx 10.6.3

[John DeNero]

Hi,

I've run into a snag with the libsdl port.  I had no problems during
installation.  I was also able to build the following simple test
case:

http://pastebin.com/YkmzghJR

Using:

gcc `sdl-config --cflags` sdl.c `sdl-config --libs`
OR
gcc -I/opt/local/include/SDL -D_GNU_SOURCE=1 -D_THREAD_SAFE sdl.c
-L/opt/local/lib -lSDLmain -lSDL -framework Cocoa

However, running the test case gives no graphical output and the
following trace.  Any ideas?

OSX: 10.6.3
MacPorts: 1.9.1
libsdl: 1.2.14

Thanks,
John
