Thanks for the tip! This is something to be taken on board in an eventual port

See my replies to René on this point.

So why is it failing for me? See the kcoreaddons log in the tarball attached to my
first message on this thread.

That's because you never used CMAKE_AUTOMOC_RELAXED_MODE=TRUE,
I suppose. It's what caused the problem for me.
Still and all, it is odd that the main.cpp in frameworks/kio/src/kcms/kio can build when there
is no main.h for MOC to work on… Is it picking up the main.h in a neighbouring sub-tree?
Is that correct? Why does it work? Why is the file called main.cpp when it is not a main()
program? Makes no sense to me.

Wish I'd thought of looking there… :-(

I think that is what we will have to do in an eventual Frameworks port.

Sounds like that is a problem in MacPorts, bringing in excess dependencies.

Another point to note in an eventual Frameworks port.

Could you make any sense of the logs and error messages in the tarball I sent earlier?

Maybe I should take some of my questions to kde-core-devel. We need serious help
to make Frameworks/KF5 into a "reproducible" and "deterministic" port of the standard
required by MacPorts developers (and by me: that's why I can depend on MacPorts).
My guess is that problems exist because CMake is designed to search "high and low"
for components of a build. This might be fine in the many and varied Linux environments,
where there is usually just one "authoritative" copy of a component (wherever it has been
installed), but not so good in an environment where then can be more than one "authoritative"
copy, as with OS X and MacPorts. Sometimes it picks up the wrong copy...
