RMagick 2.11.0 install fails with ImageMagick 6.5.4

Trying to install RMagick 2.11.0 was giving me the following error:

Installing ImageMagick 6.5.5 fixes all this though. Was there a typo
in the required ImageMagick version for the build script?

RMagick 2 works with ImageMagick 6.3.0 and later.

Line 98 in mkmf.log says "/usr/bin/ld: cannot find -lltdl". That is, ld
failed because ImageMagick says it needs libltdl.so but that library
couldn't be found. Googling "imagemagick libltdl" uncovers a number of
questions about this library and ImageMagick. I'm guessing that some
change to ImageMagick 6.5.5 configuration resolved the problem.
