ImageMagick's 'convert' command fails due to FontConfig Error

The issue is that fontconfig requires /etc/fonts/fonts.conf file, which MacOS likely does not have, unless it uses fontconfig itself. So we would either need to patch fontconfig to look into a fallback path when that does not exist, or work around it by setting FONTCONFIG_FILE environment variable as folllows:

          # Fontconfig error: Cannot load default config file
          FONTCONFIG_FILE = makeFontsConf {
            fontDirectories = [ freefont_ttf ];
          };
