Subject: Curious link error: symbols not found

Hi,
just today I tried to compile "ktouch", a KDE and QT application.
This
failed with *link* errors (see below), which I find very curious.
Let's look at the first error message: To my understanding.the
package
"kcmutils" should reference to *exactly* the version of Qt (or what
ever), it was build for. So how can it be that some symbol is not
found?
I tried force-re-building qtbase and the effected packed (as listed
below), but this did not solve the issue.
/gnu/store/…-kcmutils-5.28.0/lib/libKF5KCMUtils.so.5.28.0:
undefined reference to `qt_version_tag@Qt_5.7'
[...]
Perhaps the monolithic Qt (which is at 5.6x) as well as the modular
Qt are in your profile? If the so from the monolithic Qt is found by
the linker (or already at profile creation time, as I think the 2 Qt
versions would lead to collisions), maybe such errors could occur?
