I also get this message when trying to update ImageMagick:

ImageMagick seems to require a backward version... are we back to RPM's
dependency nightmares?  How can I fix this?

You are missreading that.  ImageMagick-c++ is what needs the old version.
Sound like whoever built ImageMagick-c++ has not rebuilt it for the new

Yum is there to resolve rpm dependacy problems, but it cannot do so if
people do not rebuild packages with hard dependancies in the first place.

If package A depends on package Z version 1.0 and package Z gets updated
to version 1.1, package A has to be rebuilt so it can be upgraded as well.

There is a newer version of ImageMagick-c++ which matches the other
two packages being installed. The OP did not download it. Perhaps he
was not aware of its availability?

If he is using Yum, it should download it as well. (Assuming it is on one of the repositories that Yum is configured for.)

There are a couple of things that could be happening here though. I noticed that he is using an x86_64 build. In that case you can get some weird problems that Yum does not quite handle correctly.

If you tell yum to "yum update ImageMagick" and it has only one architecture of ImageMagick-c++ available, it will give you that warning without telling you which architecture it is failing for. This is due to the weird quirk that on that platform you can have both 32 bit and 64 bit packages installed at the same time. (I have an AMD64 laptop. I see that problem every once in a while. Especially if the i386 packages get deprecated or never get added to the x86_64 repository.)
