Portage fails to resolve cases when two packages depend on each other due to some use flags enabled. Reproducible: Always Steps to Reproduce: These loops are actual: freetype[harfbuzz] -> harfbuzz[freetype] -> freetype ncurses[gpm] -> gpm -> ncurses mesa[vaapi] -> libva; libva[opengl] -> virtual/opengl -> mesa Also cups[zeroconf] caused problems in past, but now it seems to be fixed (I just can't track it by look into ebuilds). Actual Results: At least it reports, where is problem, propose manual solution by disabling flags, masking, etc. Expected Results: Should try multiple emerges for same package. First time with USE=-flag for whatever flag causing circular dependency, second time with this flag on.
