The only info I can find is this:  https://guide.macports.org/chunked/reference.portgroup.html <https://guide.macports.org/chunked/reference.portgroup.html>  and it doesn’t say anything about qt4 or qmake.  Currently, the OpenModelica port doesn’t use portgroups.  Any suggestions for how to potentially get that port to use, would be very helpful.  That could potentially include incorporation of portgroups in the port.  The existing port works with qt4 4.8.7_1 and now fails with 4.8.7_2, and I am not really sure what variables are necessary, or how to fix it.
