I don't know why, it probably the official name of the upstream project, |
| 14 |
like kde4 really is kde4 not kde. Names are arbitrary anyway. Why the |
| 15 |
name xfce? Maybe it means something, it probaly doesn't |

No it doesn't mean that. It means that according to the configuration |
| 31 |
you have specified, lprng and cups must both be installed, but they |
| 32 |
cannot coexist on the same system (i.e. they block). |
| 33 |
|
| 34 |
You, the human, must now make a decision and tell portage what you want |
| 35 |
it to do, and you need to tell it in the unambiguous manner that |
| 36 |
portage expects you to tell it in. You may be quite certain that you |
| 37 |
have done this, but I assure you you have not (according to portage's |
| 38 |
rules that is) |

We'll need lots more info to determine why portage wants to do this. |
| 49 |
Start with the output of 'emerge -avt xfce4' and post all of it back |
| 50 |
here. |
| 51 |
|
| 52 |
Meanwhile, I recommend you get out the trusty gentoo docs from |
| 53 |
gentoo.doc and read the section on blockers, as you are going to need |
| 54 |
this info. My bet is that you have the cups USE flag enabled (to enable |
| 55 |
printing) and xfce4 is hard-coded to use cups as the default print |
| 56 |
daemon. Before you ask "why is there not a choice?" - there is, it's |
| 57 |
called a virtual, but in the absense of you saying which package you |
| 58 |
want to satisfy that virtual, there must be a default. cups would be a |
| 59 |
good default choice, lprng would be an very thick choice. |
