Dear All, Apologies - its another mac question! I went through the instruction on installing Demeter on Mac OSX, installed Macports successfully. I then tried to install Demeter, and got an error message. So I installed xorg server separately, no error message, and then tried Demeter again, with the following command and response. I noticed when installing xorg that the pgplot was pgplot +gcc49, not +gcc48, which the Demeter installation seems to be looking for. Athena opens and does stuff but no plot window. Has anyone experienced and resolved this? Thanks, cheers, Katy $sudo port install demeter-devel ---> Computing dependencies for ifeffit ---> Fetching distfiles for ifeffit Error: Install pgplot +gcc48 Error: org.macports.fetch for port ifeffit returned: pgplot +gcc48 not installed Please see the log file for port ifeffit for details: /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_science_ifeffit/ifeffit/main.log Error: Unable to upgrade port: 1 Error: Unable to execute port: upgrade ifeffit failed
