I have updated a few software packages on my Tumbleweed system a moment ago.

zypper 1.12.4-1.2
libzypp 15.6.0-1.1


Now I wonder about error messages like the following.

Sonne:~ # zypper se mozilla
zypper: /usr/local/lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found
(required by zypper)
zypper: /usr/local/lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found
(required by /usr/lib64/libzypp.so.1505)


Should the corresponding RPM packages express such a dependency explicitly so
that the needed software libraries will stay consistent?
