When USE=gtk and USE=mono are set, avahi depends on dev-dotnet/gtk-sharp. My system has version 1.0.10 of gtk-sharp installed; the latest version is 2.10.0. So, my old version satisfied the ebuild dependency, but a build failure resulted: Making all in avahi-ui-sharp make[2]: Entering directory `/var/tmp/portage/net-dns/avahi-0.6.22/work/avahi-0.6.22/avahi-ui-sharp' mcs -keyfile:../avahi-sharp/avahi.snk -target:library -out:avahi-ui-sharp.dll -debug ./ServiceDialog.cs -pkg:gtk-sharp-2.0 -r:../avahi-sharp/avahi-sharp.dll -r:Mono.Posix ./gencfg.sh ../avahi-common/libavahi-common.la < avahi-ui-sharp.dll.config.in > avahi-ui-sharp.dll.config Package gtk-sharp-2.0 was not found in the pkg-config search path. Perhaps you should add the directory containing `gtk-sharp-2.0.pc' to the PKG_CONFIG_PATH environment variable No package 'gtk-sharp-2.0' found error CS8027: Error running pkg-config. Check the above output. make[2]: *** [avahi-ui-sharp.dll] Error 1 To fix this, I believe the dependency on dev-dotnet/gtk-sharp should be changed to >=dev-dotnet/gtk-sharp-2.0.0. When I make this change locally, the build succeeds.
