Come to find out, it unfortunately was not as simple as just installing the components one-by-one to find the offender. openSUSE 
apparently provides for conditional dependencies.

Installation of 'gambas3-ide' triggered the installation of 'qt6-base-common-devel', but not all by itself.


Manually walking the dependency tree in reverse:

i  | qml-autoreqprov | Automatic dependency generator for QML files and modules | package

As side note, 'qml-autoreqprov' doesn't unconditionally require 'qt6-base-common-devel'. It is conditionally dependent on if 
'libQt6Qml6' is installed.

Summary        : Automatic dependency generator for QML files and modules
Description    :
    Automatic dependency generator for QML files and modules.
    If installed, rpm uses this to generate Requires of .qml files
    and Provides of QML modules.

    (qt6-base-common-devel if libQt6Qml6)  '<--- this conditional dependency
    (qt6-declarative-tools if libQt6Qml6)
~~~~~~

'libQt6Qml6' is installed due to the installation of 'gambas3-gb-qt6'.

Resuming manually walking the dependency tree in reverse:
~~~~~~
user@localhost:~> zypper search --installed-only --requires --recommends qml-autoreqprov
Loading repository data...
Reading installed packages...

S  | Name                  | Summary                  | Type
---+-----------------------+--------------------------+--------
i  | libQt6Qml6            | Qt 6 Qml library         | package
i  | libQtQuick5           | Qt 5 Declarative Library | package
i  | qt6-declarative-tools | Qt 6 Declarative Tools   | package
~~~~~~

'libQtQuick5' was already installed prior to the installation of Gambas3.

There is a somewhat circular dependency between 'qt6-declarative-tools' and 'qml-autoreqprov', and no definitive dependency link.

There are quite a few Qt6 packages that require 'qt6-base-common-devel'. I discovered what is triggering the installation of 
'qt6-base-common-devel' only by querying what 'libQt6Qml6' requires.

    (qml-autoreqprov if rpm-build)  '<--- this conditional dependency
    /sbin/ldconfig
~~~~~~


So, it is the installation of 'rpm-build' which is recommended by 'gambas3-ide' that is indirectly triggering the installation 
of 'qt6-base-common-devel'.


(Is Arch packaging this convoluted?)
