I'm trying to install Gentoo following Sakaki's EFI Install Guide (i.e, crypted partition, lvm, stage1 to stage3, systemd, etc.). All is OK just to "Updating @world to Reflect the New Profile" (i.e., plasma-systemd). At this point, I meet a problem of blocked packages (Error: The above package list contains packages which cannot be installed at the same time on the same system):

(sys-apps/systemd-226-r2:0/2::gentoo, ebuild scheduled for merge) pulled in by
>=sys-apps/systemd-207 required by (sys-apps/gentoo-systemd-integration-4:0/0::gentoo, ebuild scheduled for merge)

(sys-fs/udev-225:0/0::gentoo, installed) pulled in by
>=sys-fs/udev-208-r1 required by (virtual/udev-215:0/0::gentoo, installed)

I know there are big discussions concerning the relationship between udev and systemd, but I don't understand what I should do in my specific situation. Could a patient guru kindly help me (a half-newbie!), in simple terms, to go further in my friendship with our marvellous Gentoo? And, I'd say, to understand what is happening?
Many thanks.

Short answer is that systemd incorporates the functionality of udev, if you are running systemd you have to remove udev.
Code:
emerge -Cpv sys-fs/udev
and re-run your @world update should fix this.
Covered in the wiki at: https://wiki.gentoo.org/wiki/Systemd#Installation if you would like to read more.

Hi ian.au, thanks for your help. I understood that udev should be removed, but I wasn't sure that this could be done without future problems.
In my specific case, it has been necessary to proceed in this manner:

(1) emerge --deselect sys-fs/udev
(2) USE="-qt5" emerge cmake
(3) emerge --ask --verbose --deep --with-bdeps=y --newuse --update @world
(4) dispatch-conf
(4) emerge cmake
....

Again thanks by giocitta the half-newbie.
