===> The following configuration options are available for rubygem-mini_magick-4.9.2_1:
X11=on: X11 (graphics) support
====> ImageMagick image processing support: you have to select exactly one of them
IMAGEMAGICK6=on: Use ImageMagick 6.x (graphics/ImageMagick6)
IMAGEMAGICK7=off: Use ImageMagick 7.x (graphics/ImageMagick7)
===> Use 'make config' to modify these settings
Update ImageMagick to 188.8.131.52 
* Add PKGNAMESUFFIX and rename the directory. This was done to show
that IM6 is not the "main" version. But still fully supported by upstream.
* Convert a number of options to optionhelpers.
* Add option for ISO/IEC 23008-12:2017 HEIF suport
* Add comment to pkg-descr explaining IM6's "legacy" tag.
* Add comment to the patch-config_policy.xml file why it still needed.
Please note that IM7 is not a drop in replacement due to library API and
command arguments changes. And as a result ports need to decide for themself
which version to use.
Chase these changes in all the ports that using IM6.
