Dear all, I would like to install Demeter on Mac device. I followed all the instructions with "Installing Demeter on the Mac" in the website. But in the terminal window, when i write : "sudo port install xorg-server demeter", this message appears : "Error: Port xorg-server not found". Did someone had already receive this type of message? Or know a way to install the program. Thanks for your help. -- Laurane Léost
