It turns out that for the moment 2. didn’t work, as you had suggested, it seems that there is a bug that the OpenModelica has to fix for the new qt4-mac layout. Is there any documentation, or hints, explaining the new layout, or what changes might be necessary? Any guidance that I can pass along to those developers would be appreciated. For now, I ended up doing 2, then having to downgrade qt4-mac as well, to get it to build, ,then having to downgrade a few other ports, to go with the old qt4-mac layout.
