libstdc++ 7.3 or 9.0 ?

[Makoto Fujiwara <makoto%if.t.u-tokyo.ac.jp@localhost>]

In the pbulk log:
  http://www.ki.nu/pkgsrc/reports/current/NetBSD-9.0/20250329.0421/phonon-qt5-4.11.1nb24/build.log
It seems to me (not for sure)
the part of problem is:
--------------------
/usr/bin/ld: warning: libstdc++.so.9, needed by /tmp/multimedia/phonon-qt5/work/.buildlink/qt5/lib/libQt5Widgets.so, may conflict with libstdc++.so.7
collect2: error: ld returned 1 exit status
gmake[2]: *** [phonon/CMakeFiles/phonon4qt5.dir/build.make:667: bin/libphonon4qt5.so.4.11.1] Error 1
gmake[1]: *** [CMakeFiles/Makefile2:2056: phonon/CMakeFiles/phonon4qt5.dir/all] Error 2
gmake: *** [Makefile:146: all] Error 2
*** Error code 2
--------------------
(I'm afraid this may not be a main problem of build failure, but)

I did another single /limited-list pbulk for phonon-qt5, 
on the newly installed NetBSD/amd64 9.4 box:
and getting the same problem as above:

I've checked the libstdc++ versions after pbulk failure
------------------------
thinkc-01# pkg_info  |grep gcc12
gcc12-12.4.0nb1     The GNU Compiler Collection (GCC) - 12.0 Release Series
gcc12-libs-12.4.0nb3 The GNU Compiler Collection (GCC) support shared libraries
------------------------
there are two sets of libstdc++.so are found as shown below
 libstdc++.so.7  from gcc12-12.4.0nb1            (newly packaged)
 libstdc++.so.9  from base system of release 9.4 

are these expected situation ?
