# https://github.com/Imagick/imagick/commit/5ae2ecf20a1157073bad0170106ad0cf74e01cb6 (causes a lot of build failures, but strangely only intermittent ones)
# see also https://github.com/Imagick/imagick/pull/641
# this is "pecl install imagick-3.7.0", but by hand so we can apply a small hack / part of the above commit
# Thanks to @tianon https://github.com/docker-library/wordpress/commit/509adb58cbc7463a03e317931df65868ec8a3e92
