Hi, |
| 2 |
|
| 3 |
doing the weekly "emerge --sync" and "emerge -aDuv @world", portage |
| 4 |
suddenly asks me to set the "harfbuzz" USE flag for "freetype". The |
| 5 |
exact messages are |

emerge: there are no ebuilds built with USE flags to satisfy |

">=media-libs/freetype-2.5.0.1:2=[harfbuzz,png,abi_x86_32(-)?,abi_x86_64(-)?,abi_x86_x32(-)?,abi_mips_n32(-)?,abi_mips_n64(-)?,abi_mips_o32(-)?,abi_s390_32(-)?,abi_s390_64(-)?]". |

!!! One of the following packages is required to complete your request: |
| 12 |
- media-libs/freetype-2.10.4::gentoo (Change USE: +harfbuzz) |
| 13 |
(dependency required by "x11-libs/pango-1.48.7::gentoo" [ebuild]) |
| 14 |
(dependency required by "net-analyzer/rrdtool-1.7.2-r100::gentoo[graph]" [installed]) |
| 15 |
(dependency required by "net-mail/mailgraph-1.14-r2::gentoo" [installed]) |
| 16 |
(dependency required by "@selected" [set]) |
| 17 |
(dependency required by "@world" [argument]) |

on my 32-bit Gentoo. On my 64-bit Gentoo, it looks pretty similar: |

The following USE changes are necessary to proceed: |

(see "package.use" in the portage(5) man page for more details) |

Of course, I just could do that, but "equery u freetype" tells me for |
| 37 |
"harfbuzz": "WARNING: may trigger circular dependencies!" |
| 38 |
|
| 39 |
Some googling showed me that circular dependencies seem to be a very, |
| 40 |
very ugly thing which you can't easily get rid of. |
| 41 |
|
| 42 |
Just turning off all unneeded USE flags isn't easy either - for example, |
| 43 |
I'm using mailgraph for graphical display on my website, which needs |
| 44 |
rrdtool[graph], which needs pango, which needs freetype... and there |
| 45 |
are some more dependencies on *real* used packages. |
| 46 |
|
| 47 |
How should I proceed, avoiding circular dependencies? |

Thank you in advance, |
