Thanks.  My /usr/portage/profiles/base/make.defaults has

PYTHON_TARGETS="python2_7 python3_3"
PYTHON_SINGLE_TARGET="python2_7"

The error message was

  The following REQUIRED_USE flag constraints are unsatisfied:
    python? ( exactly-one-of ( python_single_target_python3_3
    python_single_target_python3_4 python_single_target_python2_7 ) )

It looks to me like make.defaults sets exactly one of those.  Is it
possible my USE="-* wipes out use_expand things as well?
