Created attachment 613896 [details] emerge --info I get the following error when emerging any of plasma-vault-5.18.0 , powerdevil-5.18.0 or plasma-nm-5.18.0 : -- Configuring done CMake Error in kded/CMakeLists.txt: Imported target "KF5::NetworkManagerQt" includes non-existent path "/usr/lib64/libffi-3.3_rc0/include" in its INTERFACE_INCLUDE_DIRECTORIES. Possible reasons include: * The path was deleted, renamed, or moved to another location. * An install or uninstall procedure did not complete successfully. * The installation package was faulty and references files it does not provide. CMake Error in kded/CMakeLists.txt: Imported target "KF5::NetworkManagerQt" includes non-existent path "/usr/lib64/libffi-3.3_rc0/include" in its INTERFACE_INCLUDE_DIRECTORIES.

This is with kde-frameworks/networkmanager-qt-5.67.0 I have dev-libs/libffi-3.3-r1 installed, which does NOT create a folder /usr/lib64/libffi-3.3-r1 , but rather /usr/lib64/libffi . Creating a symlink did not fix this, so it seems like NetworkManager-Qt looks for 3.3_rc0 specifically. Note that virtual/libffi is still at version 3.3_rc0 Installing dev-libs/libffi-3.3_rc0 instead of libffi-3.3-r1 fixes this. In summary, there's two issues: First, the versions of virtual/libffi and dev-libs/libffi do not match, and kde-frameworks/networkmanager-qt looks for the version of the virtual package Second, dev-libs/libffi-3.3-r1 installs incorrectly, since the folder in /usr/lib64 does not include the package version, which networkmanager-qt would be looking for Attached is the output of emerge --info
