yes may be... if so, I would like to know the reason :-) |

If you build a binary with different USE flags then on the target it |
| 19 |
would be merged as ebuild and not as binary. But this seems only to work |
| 20 |
with --usepkg not with --getbinpkg. ?? CFLAGS handling is done in the same |
| 21 |
way like USE flags. You can use the tbz2tool to split your binary into |
| 22 |
data (tar) and info (text). In this info-text is every thing stored like |
| 23 |
USe, CFALGS, .... |

Hm... yes every time you type emege .... it will be recorded in the |
| 34 |
world-file, expect emerge --oneshot (-1)... so my explicit merge will not |
| 35 |
be recorded in world it stays what it was before (world or dependency). |

So I understand --usepkg in this way to use binary if all USE/C flags etc |
| 38 |
match. If not fallback to ebuilds. So I know I have the right binary pkgs, |
| 39 |
why does: |
| 40 |
|
| 41 |
emerge -uDpv --newuse world |
| 42 |
|
| 43 |
and |
| 44 |
|
| 45 |
emerge -uDpv --newuse --usepkg world |
| 46 |
|
| 47 |
show different results? |
