ImageMagick and OS X Lion trouble

brew uninstall imagemagick
brew install imagemagick --build-from-source

worked for me

On 10.8 I solved this issue with:

brew install libtool --universal
brew link libtool

If you don't know what brew is, visit https://github.com/mxcl/homebrew and its wiki.

I also upgraded to Lion and lost ImageMagick, although i'm getting different errors.

i found a Lion distribution on imagemagick.org. not a big fan of the DYLD_LIBRARY_PATH environment variable but it works.

ok scratch that. i just downloaded the ImageMagick source and re-compiled:

cd /tmp
curl -OL ftp://ftp.imagemagick.org/pub/ImageMagick/ImageMagick.tar.gz
tar -xzf ImageMagick.tar.gz
cd ImageMagick-6.7.2-7/
./configure --prefix=/usr/local --disable-static --with-modules --without-perl --without-magick-plus-plus --with-quantum-depth=8 --disable-openmp --with-gs-font-dir=/usr/local/share/ghostscript/fonts
make
sudo make install

I too use homebrew for installing packages but imagemagick stopped working after upgrading OSX 10.8 to 10.9 (Mavericks). I had to do the following steps:

brew uninstall imagemagick
brew uninstall libtool
brew install libtool --universal
brew install imagemagick --build-from-source

Why the --build-from-source? Well for me running brew install imagemagick on its own to install the pre-built binary wasn't sufficient; it fixed the original 'dyln' error but was replaced with:

unable to load module `/usr/local/Cellar/imagemagick/6.8.7-7/lib/ImageMagick//modules-Q16/coders/png.la': file not found @ error/module.c/OpenModule/1277
