* IMPORTANT: config file '/etc/portage/package.use/mate' needs updating.These are the packages that would be merged, in reverse order:Calculating dependencies * See the CONFIGURATION FILES and CONFIGURATION FILES UPDATE TOOLS * sections of the emerge man page to learn how to update config files........ done!!!! Multiple package instances within a single package slot have been pulled!!! into the dependency graph, resulting in a slot conflict:net-misc/curl:0 (net-misc/curl-7.49.0:0/0::gentoo, installed) pulled in by (no parents that aren't satisfied by other packages in this slot) (net-misc/curl-7.49.0:0/0::gentoo, ebuild scheduled for merge) pulled in by net-misc/curl[curl_ssl_gnutls(-)=,curl_ssl_nss(-)=,curl_ssl_openssl(-)=,-curl_ssl_axtls(-),-curl_ssl_cyassl(-),-curl_ssl_polarssl(-)] required by (dev-python/pycurl-7.19.3.1-r2:0/0::gentoo, ebuild scheduled for merge)!!! Enabling --newuse and --update might solve this conflict.!!! If not, it might help emerge to give a more specific suggestion.The following USE changes are necessary to proceed: (see "package.use" in the portage(5) man page for more details)# required by net-libs/webkit-gtk-2.10.9::gentoo# required by net-libs/gnome-online-accounts-3.18.4::gentoo# required by net-libs/libgfbgraph-0.2.3::gentoo# required by media-gfx/gnome-photos-3.18.3-r1::gentoo# required by gnome-base/gnome-extra-apps-3.18.0::gentoo[tracker]# required by gnome-base/gnome-3.18.0::gentoo[extras]# required by gnome-base/gnome (argument)>=media-libs/harfbuzz-1.1.3 icu# required by media-gfx/gnome-photos-3.18.3-r1::gentoo# required by gnome-base/gnome-extra-apps-3.18.0::gentoo[tracker]# required by gnome-base/gnome-3.18.0::gentoo[extras]# required by gnome-base/gnome (argument)>=media-plugins/grilo-plugins-0.2.17 upnp-av# required by media-gfx/gnome-photos-3.18.3-r1::gentoo# required by gnome-base/gnome-extra-apps-3.18.0::gentoo[tracker]# required by gnome-base/gnome-3.18.0::gentoo[extras]# required by gnome-base/gnome (argument)>=dev-libs/libgdata-0.17.4-r1 gnome-online-accounts# required by sys-apps/systemd-226-r2::gentoo# required by x11-wm/mutter-3.18.2-r1::gentoo[kms]# required by gnome-base/gnome-3.18.0::gentoo# required by gnome-base/gnome (argument)>=sys-apps/dbus-1.10.8-r1 systemd# required by media-libs/clutter-1.24.2::gentoo[egl]# required by x11-wm/mutter-3.18.2-r1::gentoo[kms]# required by gnome-base/gnome-3.18.0::gentoo# required by gnome-base/gnome (argument)>=media-libs/cogl-1.22.0-r2 gles2# required by x11-wm/mutter-3.18.2-r1::gentoo[kms]# required by gnome-base/gnome-3.18.0::gentoo# required by gnome-base/gnome (argument)>=media-libs/clutter-1.24.2 egl# required by media-plugins/grilo-plugins-0.2.17::gentoo# required by media-gfx/gnome-photos-3.18.3-r1::gentoo# required by gnome-base/gnome-extra-apps-3.18.0::gentoo[tracker]# required by gnome-base/gnome-3.18.0::gentoo[extras]# required by gnome-base/gnome (argument)>=media-libs/grilo-0.2.15 playlist# required by media-sound/pulseaudio-8.0::gentoo[alsa,alsa-plugin]# required by gnome-base/gnome-control-center-3.18.2::gentoo# required by net-libs/gnome-online-accounts-3.18.4::gentoo[gnome]# required by net-libs/libgfbgraph-0.2.3::gentoo# required by media-gfx/gnome-photos-3.18.3-r1::gentoo# required by gnome-base/gnome-extra-apps-3.18.0::gentoo[tracker]# required by gnome-base/gnome-3.18.0::gentoo[extras]# required by gnome-base/gnome (argument)>=media-plugins/alsa-plugins-1.0.29 pulseaudioWould you like to add these changes to your config files?
