Can't find Magick-config

Question

I am getting the following error when I try to run my dev console (MAC OS X / Snow Leopard). Does anyone know the solution?

/usr/local/bin/ruby extconf.rb
checking for Ruby version >= 1.8.5... yes
checking for gcc... yes
checking for Magick-config... no
Can't install RMagick 2.13.1. Can't find Magick-config in .:/usr/local/bin:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin

*** extconf.rb failed ***
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.

Answer 1

I had a similar problem because I didn't include a library for a specific gem. Check your gems and see if they depend on a library which image gems always do.

config.gem gem_name, :lib => 'path_of_your_library'
