[Ifeffit] Demeter-devel port added in Macports for OS X

OS X Users, I have created a new port in Macports for demeter-devel based on the 0.9.20 version which is still in development. This has important fixes for the black window problem in Artemis. To install it, simply run the following commands in Terminal: sudo port selfupdate sudo port uninstall demeter sudo port install demeter-devel Feedback appreciated. I have only tested it on OS X 10.9.3 so far. Just keep in mind that the “devel” part means that this is not a release version and problems may exist. Cheers! Frank
