Created attachment 545014 [details] Full log of emerge and for khelpcenter, emerge with xapian and khelpcenter and emerge --info Hi, it appears installing plasma-meta and specifically khelpcenter fails. One of the error is: > xapiansearch.cpp:(.text.startup+0xb28): undefined reference to `Xapian::Query::get_description[abi:cxx11]() const' It also appears, from a quick googling around that the needed version of xapian is not being pulled by the khelpcenter package. The output of emerge -pv plasma-meta > [ebuild N ] kde-apps/khelpcenter-18.04.3:5::gentoo USE="handbook -debug" 0 KiB > [ebuild N ] kde-plasma/plasma-meta-5.12.5:5::gentoo USE="bluetooth crypt display-manager gtk handbook pam pulseaudio sddm wallpapers -grub -legacy-systray -networkmanager -plymouth -sdk" 0 KiB The output of emerge -pv xapian > [ebuild U ] dev-libs/xapian-1.4.5:0/30::gentoo [1.4.4:0/30::gentoo] USE="chert glass inmemory -doc -static-libs" ABI_X86="(64) -32 (-x32)" CPU_FLAGS_X86="sse sse2" 2,745 KiB I resolved by doing emerge xapian plasma-meta.

Not a dependency issue. This looks like xapian was not rebuilt after a switch from GCC4 to 5 (incompatible ABI).
