Right, thanks. Note that sys-fs/udev is not on my system, the conflict |
| 43 |
occurs because portage wants to emerge it. I am trying to downgrade the |
| 44 |
virtual udev. |
| 45 |
|
| 46 |
I tried your suggestion as follows |
| 47 |
|
| 48 |
* quickpkg'ed |
| 49 |
sys-app/systemd virtual/udev sys-app/gentoo-system-integration |
| 50 |
|
| 51 |
* unmerged all three |
| 52 |
|
| 53 |
* merged the desired virtual/udev version with --nodeps |
| 54 |
(it wouldn't work without --nodeps) |
| 55 |
|
| 56 |
* tried to emerge the desired versions of the other two |
| 57 |
(without using --nodeps) |
| 58 |
|
| 59 |
This last step fails because it seems (assuming I am reading the emerge |
| 60 |
tree output correctly, see below) that dev-libs/lubusbx-1.0.17:1 requires |
| 61 |
virtual/udev-206. |
| 62 |
|
| 63 |
But I don't see that version dependence in the ebuild. Moreover this is |
| 64 |
the only version of libusbx in the tree so (again assuming I am reading |
| 65 |
the tree correctly) this says that gnome 3.6 requires |
| 66 |
virtual/udev-206-r2, which seems strange. Indeed, canek has said that |
| 67 |
gnome has trouble with systemd-206 (which virtual/udev-206 would bring |
| 68 |
it). |
| 69 |
|
| 70 |
So I did the emerge -K you suggested and am back where I started. |
| 71 |
|
| 72 |
Any help would be appreciated. |

I am hoping not to have to do that (or emerge --nodeps). |

It may be possible to solve this problem by using package.mask to |
| 138 |
prevent one of those packages from being selected. However, it is also |
| 139 |
possible that conflicting dependencies exist such that they are |
| 140 |
impossible to satisfy simultaneously. If such a conflict exists in |
| 141 |
the dependencies of two different packages, then those packages can |
| 142 |
not be installed simultaneously. You may want to try a larger value of |
| 143 |
the --backtrack option, such as --backtrack=30, in order to see if |
| 144 |
that will solve this conflict automatically. |

Use --autounmask-write to write changes to config files (honoring |

CONFIG_PROTECT). Carefully examine the list of proposed changes, |

paying special attention to mask or keyword changes that may expose |
