Hi, doing the weekly "emerge --sync" and "emerge -aDuv @world", portage suddenly asks me to set the "harfbuzz" USE flag for "freetype". The exact messages are
--- cut here --- 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: - media-libs/freetype-2.10.4::gentoo (Change USE: +harfbuzz) (dependency required by "x11-libs/pango-1.48.7::gentoo" [ebuild]) (dependency required by "net-analyzer/rrdtool-1.7.2-r100::gentoo[graph]" [installed]) (dependency required by "net-mail/mailgraph-1.14-r2::gentoo" [installed]) (dependency required by "@selected" [set]) (dependency required by "@world" [argument]) --- cut here --- on my 32-bit Gentoo. On my 64-bit Gentoo, it looks pretty similar: --- cut here --- The following USE changes are necessary to proceed: (see "package.use" in the portage(5) man page for more details) # required by x11-libs/pango-1.48.7::gentoo # required by net-analyzer/rrdtool-1.7.2-r100::gentoo[graph] # required by net-mail/mailgraph-1.14-r2::gentoo # required by @selected # required by @world (argument) >=media-libs/freetype-2.10.4 harfbuzz --- cut here --- Of course, I just could do that, but "equery u freetype" tells me for "harfbuzz": "WARNING: may trigger circular dependencies!" Some googling showed me that circular dependencies seem to be a very, very ugly thing which you can't easily get rid of. Just turning off all unneeded USE flags isn't easy either - for example, I'm using mailgraph for graphical display on my website, which needs rrdtool[graph], which needs pango, which needs freetype... and there are some more dependencies on *real* used packages. How should I proceed, avoiding circular dependencies? Thank you in advance, -Matt
