Created attachment 744669 [details]
full issue example

Portage will for some reason try to pull in both `sys-cluster/mpich` and `sys-cluster/openmpi` given the following RDEPEND specification:

```
|| ( <=sys-cluster/openmpi-3.0.0 >=sys-cluster/mpich-2.0 )
```

The issue persists with `--backtrack=9999` but is solved by masking either of the two packages. The attached file lists both the full ebuild and the issue.

Would you mind including emerge --debug ... for the emerge command and emerge --info for posterity?
