On two systems I try to remove since yesterday the blocking between eselect-blas, eselect-lapack, eselect-cblas and lapack-reference. On the first'emerge -uvDN world' failed originally with: ... [ebuild U ] sci-libs/lapack-reference-3.3.1-r1 [3.2.1-r1] USE="-static-libs% -test% -xblas% (-doc%*)" 4,830 kB [0=>1] ... [blocks B ] app-admin/eselect-blas ("app-admin/eselect-blas" is blocking sci-libs/lapack-reference-3.3.1-r1) [blocks B ] app-admin/eselect-lapack ("app-admin/eselect-lapack" is blocking sci-libs/lapack-reference-3.3.1-r1) [blocks B ] app-admin/eselect-cblas ("app-admin/eselect-cblas" is blocking sci-libs/lapack-reference-3.3.1-r1) So I removed eselect-blas, eselect-lapack, eselect-cblas, blas-atlas, lapack-atlas, blas-reference, lapack-reference, clapack, R, rkwards, octave, PDL, scipy, openCV and a lot of other packages which I suspected that they have blas or lapack dependencies. I also removed the atlas, blas and lapack USE flags from /etc/make.conf. Then I installed sci-libs/atlas-3.9.47 from the science overlay, and I removed the broken links /usr/lib/libblas.*, /usr/lib/libcblas.* and /usr/lib/liblapack.*. But I do not get rid from eselect-blas, blas-reference, virtual/blas etc. 'emerge world' wants to install them again: emerge -uvDN world These are the packages that would be merged, in reverse order: Calculating dependencies ..... .... .. ... done!

I had exactly the same problem. Removing the science overlay solved the blocking problem for me. So it looks like this is a problem in one of the packages from the science overlay. Might be able to temporarily block the offending packages, if removing science completely is not an option for you (but I did not try that).
Masking these two: =virtual/lapack-3.3 =sci-libs/lapack-reference-3.3.1-r1 passes this hurdle.
