Mi instalación de imagemagick a través de brew parece no haber creado enlaces simbólicos correctamente.

Linking /usr/local/Cellar/imagemagick/7.0.7-22...
Error: Could not symlink include/ImageMagick-7/Magick++/Blob.h
/usr/local/include/ImageMagick-7/Magick++ is not writable.
Revisé Para instalar Brew's ImageMagick y arreglar su enlace simbólico pero el problema resuelto es de enlaces simbólicos rotos ya presentes, no de permisos.
Otra información útil incluye:

Warning: "config" scripts exist outside your system or Homebrew directories.
'./configure' scripts often look for *-config scripts to determine if
software packages are installed, and what additional flags to use when
compiling and linking.
Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew provided
script of the same name. We found the following "config" scripts:

Leaving kegs unlinked can lead to build-trouble and cause brews that depend on

Tenga en cuenta el barril desenlazado en el sótano.
Este problema se puede solucionar mediante el uso de
$ sudo chown -R user:group ImageMagick-7/
pero realmente me gustaría saber qué causó el problema original, y si hay mejores soluciones.
