rmagick on OSX Mavericks - "Can't find Magick-config in ..." - ruby-on-rails

Question

When I try to install rmagick on OSX Mavericks, I get this error:
ERROR: Error installing rmagick:

In ~/.bash_profile is following:
MYSQL=/usr/local/mysql/bin
export PATH=$PATH:$MYSQL
#export DYLD_LIBRARY_PATH=/usr/local/mysql/lib:$DYLD_LIBRARY_PATH
export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/
export PG_DUMP="/Applications/Postgres.app/Contents/MacOS/bin/"

#export PKG_CONFIG_PATH="/opt/local/lib/pkgconfig:$PKG_CONFIG_PATH"
export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH"
export PATH=/usr/local/bin:$PATH
There's no such a path as is in the error output, where does it comes from and how can I fix it?
Thank you.

Do you have ImageMagick installed? Install it via homebrew:
brew install imagemagick
