Solution 1

Reinstalling pkg-config solved the issue for me.

Solution 2

I had the same issue with Rmagick after upgrading to Maverick. This solved it:

brew uninstall pkg-config
brew install pkg-config
brew unlink pkg-config && brew link pkg-config

Solution 3

brew install pkg-config fixed this for me.

I'm trying to install rmagick on my Mac OS X v10.9 (Mavericks) machine. However. I get this error
```
/usr/local/bin/Magick-config: line 41: pkg-config: command not found
/usr/local/bin/Magick-config: line 47: pkg-config: command not found
/usr/local/bin/Magick-config: line 50: pkg-config: command not found

Can't install RMagick 2.13.2. Can't find the ImageMagick library or one of the dependent libraries. Check the mkmf.log file for more detailed information.
```
The lines 41,17,50,53 in Magick-config are
```

I installed ImageMagick with brew install imagemagick --build-from-source and before running gem install rmagick, I set the path to MagickCore.pc with export PKG_CONFIG_PATH=/usr/local/Cellar/imagemagick/6.8.9-1/lib/pkgconfig and the path to Wand.h with export C_INCLUDE_PATH=/usr/local/Cellar/imagemagick/6.8.9-1/include/ImageMagick-6/.

This worked for the Wand, but not for MagickCore, as I still get pkg-config: command not found.

I use Ruby 1.9.3p545 and Ruby on Rails 3.2.16.

How can I fix this problem?

  Looks like you'll need to install pkg-config or updated PATH to include it's location. Building from source expects this utility to be on the system.

  pkg-config already came installed with homebrew. what PATH do you want me to update?

  Are you sure pkg-config is in the location you specified? Check with which pkg-config. For me, it's in /usr/local/bin/pkg-config though I am using OSX 10.7.5

In my case, brew uninstall pkg-config failed so I just ran brew install pkg-config and that fixed my issue.
