Dear All, I am new to the mac and mac apps as well as not a techie either. I am trying to install the latest version of demeter (artemis, athena and heph) on my macbook using Mavericks OS. For this I followed the steps given on the site with Macports installation, then its activation step. and then I used terminal to connect and download the athena. However there was error which I thought might because of not having the windowing environment ( I am using all the words from site and dont know anything what it means). So I clicked to download X11 from XQuartz site. After that I logged out from terminal and logged in again. to check if anything changes but the following message was observed (the complete message is attached as word document but some part essentially the last portion talking about the error is pasted below. ---> Activating xorg-libXau @1.0.8_0 Error: org.macports.activate for port xorg-libXau returned: Image error: /opt/local/lib/libXau.6.dylib already exists and does not belong to a registered port.
