So |
| 62 |
../../../etc/env.d/alternatives/lapack/_current/usr/lib64/pkgconfig/lapack.pc |
| 63 |
is not a symlink to /usr/lib64/pkgconfig/reflapack.pc? |
| 64 |
That should be provided by lapack-reference using the alternative2 |
| 65 |
eclass. /usr/lib64/pkgconfig/lapack.pc is created by eselect. |

yes, you may have to delete some left over files and re-emerge |
| 75 |
lapack-reference. |
