>>> Assumptions taken during proving & planning:

  License acceptance (1 package):
  Add to /etc/portage/package.license:
    ==x11-libs/agg-2.5-r3 GPL-2 free-noncomm

  USE flag change (2 packages):
  Add to /etc/portage/package.use:
    sci-libs/lapack eselect-ldso -flexiblas
    virtual/blas eselect-ldso -flexiblas
