I unmerged eselect-cblas and eselect-blas when I had similar problems, and I
think also {blas,cblas}-reference. The eselect packages got remerged
automatically, and some block I do not remember remained, but after some
days, a deep world update finally was working again.

This looks strange. A target in the root file system? Here the log continues
like this:

No. All I can say is that I just emerged gmsh without problems on ~amd64,
both with and without the blas USE flag. The other USE flags are those:
