Created attachment 886549 [details] error message I couldn't update elogind, if failed on configure step with error message "Got argument buildtype as both -Dbuildtype and --buildtype. Pick one". See attached report. I tried both stable elogind-246.10 and unstable 252.9, both returned same error. It turned out -Dbuildtype is filled in the meson.eclass, and logic was recently changed (commit b95ea11330e446d0deb89ca7d78356cb2a7d0d06 of gentoo repo), to use not --buildtype, but -Dbuildtype. Attached you could find 'emerge --info' output as well as possible changes to fix build. I have little experience in writing or debugging ebuilds and eclasses, so my fix could be not of finest quality, sorry.

while preparing diff for my patch I realized it was fixed in gentoo repo just an hour ago. bug is no more, can be closed.
Thanks!
