Ok, so you have 2 options. 1. Downgrade qt4-mac to the version before the change in filesystem layout, and then you can activate your already-installed older version of openmodelica-devel and it will work. of course, you'll break all the ports that require the new qt4-mac layout, and if you want to continue using them, would have to downgrade them to pre-layout-change versions as well. 2. (probably the better option) Follow the InstallingOlderPort instructions, except where it tells you to look in the MacPorts Subversion repository's log to find which revision of the port to use, you'll instead be consulting the log of whatever revision control system the Open Modelica developers use for their ports, and you'll get the old version of the port from there. Then you'll install that version, possibly first uninstalling the one you already have installed, since although it will have the correct version number, it will be for the wrong qt4-mac layout. It's possible the old port (or even the new port) won't build correctly with the new qt4-mac layout. If so, that's a bug the people who provide that portfile will have to fix. _______________________________________________ macports-users mailing list macports-users@lists.macosforge.org https://lists.macosforge.org/mailman/listinfo/macports-users
