I have compiled and packaged SE for Mac. I tried to contact Q009 so he could include my build in his SourceForge-Project, but he did not answer, so...
Additionally I've removed the update code, because the files it uses to check for a new version seem not to be hosted any more, besides that it's a little buggy and so I don't have to include CURLlib.
