After depcleaning I noticed this: >>> package: sys-libs/libselinux-2.6 * - /lib64/libselinux.so.1 * used by /usr/bin/nemo (gnome-extra/nemo-3.2.0) * used by /usr/bin/nemo-connect-server (gnome-extra/nemo-3.2.0) * used by /usr/bin/nemo-open-with (gnome-extra/nemo-3.2.0) and, indeed, looking to configure.ac, it seems this dep is automagic :( dnl *** Check for libselinux *** dnl **************************** SELINUX_LIBS= msg_selinux=no AC_CHECK_LIB(selinux, is_selinux_enabled, [AC_CHECK_HEADERS(selinux/selinux.h, [AC_SEARCH_LIBS(selinux_raw_to_trans_context, selinux, [AC_DEFINE(HAVE_SELINUX, 1, [Define to 1 if libselinux is available]) SELINUX_LIBS="-lselinux" msg_selinux=yes]) ]) ]) AC_SUBST(SELINUX_LIBS)
