This error is from a multilib testing chroot. While investigating bug #820593 I encountered this error: >>> Source configured. >>> Compiling source in /var/tmp/portage-ondisk/portage/sci-libs/vtk-9.0.3-r4/work/VTK-9.0.3 ... * Source directory (CMAKE_USE_DIR): "/var/tmp/portage-ondisk/portage/sci-libs/vtk-9.0.3-r4/work/VTK-9.0.3" * Build directory (BUILD_DIR): "/var/tmp/portage-ondisk/portage/sci-libs/vtk-9.0.3-r4/work/vtk-9.0.3_build" ninja -v -j2 ninja: error: '/usr/lib64/libzip.so', needed by 'lib64/libvtkIONetCDF-9.0.so.9.0.3', missing and no known rule to make it * ERROR: sci-libs/vtk-9.0.3-r4::gentoo-git failed (compile phase): * ninja -v -j2 failed Not sure, what change in the tree caused this to happen. Looking through the git log for the netcdf package, didn't help either. Installing dev-libs/libzip solves the issue.

Some things, I discovered. I guess, this has to do with installing a binary version of netcdf. Unmerging dev-libs/libzip leaves preserved libs, which then wants to re-merge netcdf. Building netcdf from sources, solves the preserved libs. Rebuilding netcdf from source and then libzip from source, I can unmerge libzip without preserved libs, while first emerging libzip from source and the netcdf from source, gives a preserved libs warning, when libzip gets unmerged. From my point of view, this looks, like netcdf has an automagic dependency on libzip. Build log of netcdf with libzip installed: -- Found Math library: /usr/lib64/libm.so -- Found Zip: headers at /usr/include, libraries at /usr/lib -- library is /usr/lib64/libzip.so -- Enabling use of fill value when NC_ERANGE Build log of netcdf without libzip installed: -- Found Math library: /usr/lib64/libm.so -- Enabling use of fill value when NC_ERANGE
