I am trying to install imagemagick and on my snow leopard MacOSX with homebrew.

Answer 1

I reinstalled libjpeg from here and then unlinked and linked jpeg:

brew unlink jpeg
brew link jpeg

It fixed the error. I hope this works for you.

Answer 2

What solved it for me was updating brew then installing imagemagick:

• brew update
• brew install imagemagick
