Case in point, evolution-brutus failed rebuild due to some kind of
API/ABI changes:

checking ifaddrs.h presence... yes
checking for ifaddrs.h... yes
checking for getifaddrs... yes
checking for nanosleep... yes
checking for wand/magick-wand.h... no
configure: error:  development header not installed
error: Bad exit status from /var/tmp/rpm-tmp.18zCEt (%build)
RPM build errors:

Child returncode was: 1

So does octave-forge (although it may not be directly related to ImageMagick):

The point is that other maintainers need time, not just to rebuild,
but to track down these build failures and < 24 hours is not long
enough.  

In general it would be a good idea for those who are breaking
ABI/API/soname investigate the possible extent of the breakage by
doing some scratch builds of affected packages *before* kicking off
the changes, especially when the list of packages is over past the
15-20 number and that maintainer of the package doing the breaking
doesn't maintain most of the affected packages.  The onus should be on
the ABI/API breaker to find out the extent of the problem, possible
gotchas and possible fixes/workarounds, not the breakee.
