[gentoo-user] Big Fat Yellow Warning when emerging/unmerging wine-vanilla.

[Nikos Chantziaras]

Does someone know why I get these when emerging or unmerging 
wine-vanilla (as part of a @world upgrade followed by a depclean):

  >>> Unmerging (1 of 1) app-emulation/wine-vanilla-4.1...
  !!! Warning: Skipping wine-staging. No registered targets found.
  !!! Warning: Skipping wine-d3d9. No registered targets found.
  !!! Warning: Skipping wine-any. No registered targets found.
Something that starts with "!!!" and is printed in bright, yellow 
letters seems very, very severe. Is something broken?
