Installation failure: imagemagick +rsvg

[rhstanton]

With a fresh installation of MacPorts under High Sierra, I tried

sudo port install imagemagick +rsvg

This goes on for a while, installing dependencies, before it crashes with the error

Error: Processing of port imagemagick failed

When I try the command again, I get the same result, but only a small list of remaining dependencies, so I assume the error may be in one of these:

$ sudo port install imagemagick +rsvg
--->  Computing dependencies for ImageMagick
The following dependencies will be installed: 
 graphviz
 librsvg
 vala

Please attach the main.log file. Given #55393, I suspect the problem is not with ImageMagick, but with librsvg.

Let's call this the same thing as #55393.

Note, for the sake of terminology, that this is not a crash; it's merely the program exiting with an error message. A crash means a program performed unexpected/illegal operation and the operating system forced it to stop. This is merely the program experiencing an error, telling you about it, and exiting on its own.
