Bugzilla Bug 176765

Seems to be caused by avahi, but was fine before.  Also, if I remove avahi,
programs like ksysguard cease to function.

Reproducible: Always

Actual Results:  
# emerge -pv kdelibs

These are the packages that would be merged, in order:

Anything avahi related in package.use?

Can reproduce it here, Marius. Both with stable and testing Portage. It's
really only the kdelibs ebuild, Portage is choking on.

Only things in package.use just have avahi enabled, or are setting USE flags
for avahi, not disabled, i.e.

net-dns/avahi gdbm mono
media-sound/rhythmbox avahi

The problem is that the build planner doesn't recognize that the blocker is
invalidated when the avahi flag changes state.  Workaround:

emerge --oneshot --nodeps kdelibs && emerge --oneshot --noreplace kdelibs

Created an attachment (id=118026) [edit]
handle this case where the blocker can be avoided

This is fixed in svn r6472:6474.

This has been released in 2.1.2.6.
