I think that's a different problem. You are using blas stuff from the science |
| 63 |
overlay but the version of cblas-reference from the main tree as a higher |
| 64 |
version number than the one from the science overlay (3. something?). So you |
| 65 |
probably have to mask sci-libs/cblas-reference::gentoo. |
| 66 |
|
| 67 |
For your original problem, yes portage should solve the conflict, this is very |
| 68 |
strange, are numpy or scipy part of your world file? |
