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 |
| 9 |
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, |
| 56 |
both with and without the blas USE flag. The other USE flags are those: |
