Unable to install php7-pecl-imagick=3.4.4-r7 with alpine:20210212

Hi, I am using the edge docker image (20210212 at this time) and cannot install the php7-pecl-imagick=3.4.4-r7 package. It reports the following error:

$ docker run --rm -it library/alpine:20210212

Can anybody shed some light on what happens here and how to circumvent this? I cannot reproduce this issue when i use the latest docker image (3.13.2 at this time).
