The problem is caused by the hwdb useflag, though I had to read the udev |
| 18 |
ebuild file to understand the error message :-/ |
| 19 |
|
| 20 |
RDEPEND="${COMMON_DEPEND} |
| 21 |
hwdb? |

( |

>=sys-apps/usbutils-0.82 |
| 24 |
sys-apps/pciutils[-zlib] <<<<<<<<<<<<<< look here |
| 25 |
) |

That syntax means "if you want hwdb support in udev you must disable zlib |
| 28 |
for pciutils". I have no idea why the two are incompatible, but it sounds |
| 29 |
to me like "an implementation detail" thingy. |

In any case, if you need -zlib in one package and zlib in another you can |
| 32 |
set/unset the needed flag for just one package in /etc/portage/package.use. |
