Installing from a clean stage3, installing pcmciautils and after emerge -e world, I run into a problem related in bug #90089 Stage3 have bison installed (and virtual/yacc also) so I guess the problem lies in why sys-apps/pcmciautils is depending on dev-util/yacc rather than the virtual package and avoid file overwrite issue stated in mentioned bug. equery depends dev-util/yacc * These packages depend on dev-util/yacc: sys-apps/pcmciautils-017 (dev-util/yacc)
OK done for 017 without revbump
