Well, for starters, why emerge(1) is not emerging... |

100 |
I don't know what jinja is and I just switched over to python3 myself. |
101 |
I'm not into subtleties like 6, 7, 8, or 9. |
102 |
|
103 |
I do an emerge @world, it tells me I have slot collisions and stops. |
104 |
Following Neil B.'s advice, I try to go through the collisions and see |
105 |
what the differences are. jinja was a nice example, because there was a |
106 |
collision of the same package with itself! The only difference was the |
107 |
PYTHON_TARGET. I hoped someone could explain how I could force |
108 |
equivalency in that simple case. |

Yeah. That surprises me, actually. |

I'm trying to emerge. I'm not developing anything. |

Yes, that's always an option. On the other hand, it might be possible |
136 |
to improve gentoo so that not only the very brightest people can use |
137 |
it. Source is kind of like a vaccine - if enough people use it, it can |
138 |
help prevent the spread of viruses. |
