Thanks Ryan and Joshua, now I know why that didn't work :)
What are the appropiate flags? These http://guide.macports.org/#reference.phases.configure.universal ?
I tried with those and didn't succeed in getting SDL to compile with the 10.4 SDK. As the examples are missing, I probably used them wrong. Can you give me any pointers?
