... and now it pulls in eselect-cblas and gsl which are blocking each other:

[blocks B      ] app-admin/eselect-cblas ("app-admin/eselect-cblas" is blocking sci-libs/gsl-1.15-r2)

 * Error: The above package list contains packages which cannot be
 * installed at the same time on the same system.

  (app-admin/eselect-cblas-0.1::gentoo, ebuild scheduled for merge) pulled in by
    app-admin/eselect-cblas required by (sci-libs/cblas-reference-20030223-r4::gentoo, ebuild scheduled for merge)

  (sci-libs/gsl-1.15-r2::science, installed) pulled in by
    sci-libs/gsl required by (media-gfx/inkscape-0.48.2::gentoo, installed)
    >=sci-libs/gsl-1.15 required by (sci-mathematics/sage-5.0-r1::sage-on-gentoo, ebuild scheduled for merge)

What to do here?
