I had a look at that for a while, but doing surgery on /opt/local seemed too hairy for
me.  So I settled for the deactivate route.  It took a while to sort out the dependents of
Qt 4 and deactivate them in the correct order, ending with qt4-mac, but now it is done.

Did that.  And now, as a DBA colleague of mine used to say when he set off a long
database operation, "Cooking… Cooking…".  Three out of four cores going flat out.

Yes, I've met a few of them in my years with KDE.  For them, the journey is more
important than the destination.

Well, only an unknown number of hours to go now… :-)
