net-misc/dropbox-43 depends on dev-qt/qtwebkit, dev-libs/leveldb, dev-qt/qtsql (why it depends on qtsql I have no idea). However, these are not declared as dependencies, so if nothing else installed depends on them, an emerge -avc will remove them, leaving net-misc/dropbox with missing-dependency preserved libs: !!! existing preserved libs: >>> package: dev-qt/qtwebkit-5.9.1 * - /usr/lib64/libQt5WebKit.so.5 * - /usr/lib64/libQt5WebKit.so.5.9.1 * used by /opt/dropbox/libQt5WebKitWidgets.so.5 (net-misc/dropbox-43.3.47) >>> package: dev-libs/leveldb-1.18-r2 * - /usr/lib64/libleveldb.so.1 * - /usr/lib64/libleveldb.so.1.18 * used by /usr/lib64/libQt5WebKit.so.5 (preserved) * used by /usr/lib64/libQt5WebKit.so.5.9.1 (preserved) * - /usr/lib64/libmemenv.so.1 * - /usr/lib64/libmemenv.so.1.18 * used by /usr/lib64/libQt5WebKit.so.5 (preserved) * used by /usr/lib64/libQt5WebKit.so.5.9.1 (preserved) >>> package: dev-qt/qtsql-5.9.4 * - /usr/lib64/libQt5Sql.so.5 * - /usr/lib64/libQt5Sql.so.5.9.4 * used by /opt/dropbox/libQt5WebKit.so.5 (net-misc/dropbox-43.3.47) * used by /opt/dropbox/libQt5WebKitWidgets.so.5 (net-misc/dropbox-43.3.47) Use emerge @preserved-rebuild to rebuild packages using these libraries But because they are not declared as dependencies, emerge @preserved-rebuild will not rebuild the missing packages and will not fix the problem. Explicitly emerging these three required packages *as well* so that the dropbox dependencies are satisfied pulls in 20 packages in all, because QtWebkit pulls in ruby, and ruby pulls in ... babylon5:root:~:8 # emerge -av dev-qt/qtwebkit dev-qt/qtsql dev-libs/leveldb net-misc/dropbox These are the packages that would be merged, in order: Calculating dependencies... done!

Actually I guess it's QtWebkit that's pulling in QtSql ... but the result is the same.
dev-qt/qtwebkit is already covered.
Actually, dropbox should depend directly on qtsql: ldd /opt/dropbox/libQt5WebKit.so.5 |& grep -i sql libQt5Sql.so.5 => /usr/lib64/libQt5Sql.so.5 (0x00007fed183f8000)
And on a current system, qtwebkit doesn't pull qtsql
I have just bumped dropbox, and as far as I can see this new version now supplies libQt5Sql.so.5 and nothing uses libmemenv from leveldb. I'd like to close this bug eventually, after a newer version of dropbox is marked stable, but please let me know if this issue does still affect 81.4.195
