exiv2 didn't build for netbsd-9/aarch64:

[100%] Linking CXX executable ../bin/exiv2
/usr/bin/ld: warning: libstdc++.so.9, needed by /usr/pkg/lib/libINIReader.so.0, may conflict with libstdc++.so.7

netbsd-9 uses libstdc++.so.9, but you can see that pkgsrc tries to build
exiv2 using the pkgsrc gcc10 package. And that uses incompatible library
versions:

lib/libstdc++.a
lib/libstdc++.la
lib/libstdc++.so
lib/libstdc++.so.7
lib/libstdc++.so.7.28
lib/libstdc++.so.7.28-gdb.py
lib/libstdc++fs.a
lib/libstdc++fs.la
share/gcc-10.5.0/python/libstdcxx

I would consider the gcc10 package broken.


netbsd-10 builds exiv2 with the native compiler, so there is no such
conflict.
