Installing RMagick on Mac OS X with MacPorts

Question

With the MacPorts version of ImageMagick 6.4.4 installed, I'm getting an error installing the RMagick gem.

/opt/local/bin/ruby extconf.rb update rmagick
checking for Ruby version >= 1.8.2... yes
checking for /usr/bin/gcc-4.0... yes
checking for Magick-config... no
Can't install RMagick 2.7.0. Can't find Magick-config in
    /System/Library/Frameworks/JavaVM.framework/Versions/1.5/Commands:
    /Users/jason/.bin:/opt/local/bin:/usr/local/bin:/usr/local/mysql/bin:
    /usr/local/ec2-api-tools/bin:/opt/local/bin:/usr/bin:
    /usr/local/bin:/bin:/usr/sbin:/sbin:/usr/X11/bin

I've installed older versions of rmagick successfully. I've seen references to a dev package of ImageMagick, but it doesn't seem to be available from MacPorts.

How can I install RMagick 2.7 on Mac OS X with ImageMagick 6.4.4 from MacPorts?

I suggest using Homebrew instead of Macports. After installing Homebrew, run:

brew install imagemagick
gem install rmagick

Try this from the command line before installing the rmagick gem:

sudo port install tiff -macosx imagemagick +q8 +gs +wmf

Also have you read the installation documentation here ?

This was also helpful because of the reference back to rmagick's page and because it installed ImageMagick properly using MacPorts. – Thomas Bindzus Jun 04 '13 at 21:08

The install script can't find Magick-config in your path. Did you use a non-standard install location when you installed ImageMagick through MacPorts? Usually it goes into /opt/local/bin/

You can see where MacPorts put your Magick-config by running:

port contents ImageMagick

If you find it listed there, then make sure that the directory is included in your PATH and rerun the rmagick install.

Although rather old, this was really good advice, I got rmagick installed using the following command: PKG_CONFIG_PATH=/opt/local/lib/pkgconfig gem install rmagick – Thomas Bindzus Jun 04 '13 at 21:06
Yup this was my issue as well – Monica Wilkinson Oct 02 '13 at 11:07

I've run the install command, but I keep getting this error:

/Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- RMagick2.so (LoadError)

Turns out it correctly builds the shared object file, but the name is "wrong".

The file I get is named /Library/Ruby/Gems/1.8/gems/rmagick-2.11.1/lib/RMagick2.bundle; renaming it to RMagick2.so fixes this issue.
