Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Gem files will remain installed in /Users/XXXXXXX/.rvm/gems/ruby-1.9.2-p180/gems/rmagick-2.13.1 for inspection.

But when I do this:

$ locate Magick-config
/opt/local/bin/Magick-config
/opt/local/share/man/man1/Magick-config.1.gz
/opt/local/var/macports/software/ImageMagick/6.6.4-9_0+q16/opt/local/bin/Magick-config

/opt/local/var/macports/software/ImageMagick/6.6.5-0_0+q16/opt/local/bin/Magick-config
/opt/local/var/macports/software/ImageMagick/6.6.5-0_0+q16/opt/local/share/man/man1/Magick-config.1.gz

Any ideas?

It isn’t quite the answer to the question, but the recommended way of installing Imagemagick and Rmagick on Mac is through homebrew. It’s the only way I could get Imagemagick and Rmagick playing nicely together on Mac.
