eselect-mesa is obsolete now, it should be autoremoved on a full deep world upgrade, unless you have eselect-mesa recorded in world (/var/lib/portage/world) Does that help?
Yes, this can only be a problem if eselect-mesa made it into your world file.
emerge --deselect eselect-mesa
Cool way! i did see at now and it works well! Thank you!
