Heh, heh!  I can claim to have played a small part in that:

Also this little thread is an object lesson in what can happen with Clang:

I have seen only one or two real errors in legacy games code that Clang picked
up.  They have long since been fixed and were pretty harmless anyway, but library
code can be more complex, so keep your eyes peeled…

Great news!

From current MacPorts?  Indeed you can!  And I do.

It is not hard.  A very small number of environment variables can be used to point
everything at qt4-mac.  The main one is QTDIR=/opt/local, or wherever.  That's how
KDE guys in general moved between Qt3 and Qt4.

Well, as much as I can.  Don't forget I am a Venerable KDE Programmer [1].
One cannot keep assimilating new stuff at the same rate forever.  VMs and
CI systems have both passed me by.  I stumble a lot even with git.

Cheers, Ian W.

      interviewer on dot.kde.org, meant to write "veteran", or even "venereal" :-)
