Given that in the general case the package manager can't change the |
| 13 |
active provider and will have to bail with an appropriate message that |
| 14 |
the user needs to change it themselves, the obvious solution to this is |
| 15 |
the previously-discussed-somewhere-I-can't-remember ebuild function, |
| 16 |
called on depgraph creation, to check that it will be able to compile |
| 17 |
in the current system environment. It's considerably simpler and more |
| 18 |
generally useful than subverting DEPEND to add weird special-case hacks |
| 19 |
to it. |
