As in FL-10104 with dev-php/pecl-apcu, there are several other autogens in the tree that need a SRC_URI manually set to artifacts[0].src_uri in order to function properly. These have been identified by my CDN mirroring script:
cdn@direct ~/funtoo-metatools $ bin/distfile-kit-fetch core-server-kit next [WARNING 19:56:40] No hashes for {'src_uri': ['https://pecl.php.net/get/imagick-3.7.0.tgz'], 'name': 'imagick-3.7.0.tgz'} [WARNING 19:56:40] No hashes for {'src_uri': ['https://pecl.php.net/get/raphf-2.0.1.tgz'], 'name': 'raphf-2.0.1.tgz'} [WARNING 19:56:40] No hashes for {'src_uri': ['https://pecl.php.net/get/xdiff-2.0.1.tgz'], 'name': 'xdiff-2.0.1.tgz'} [WARNING 19:56:40] No hashes for {'src_uri': ['https://pecl.php.net/get/pecl_http-4.2.3.tgz'], 'name': 'pecl_http-4.2.3.tgz'}
The needed fix for the template should be identical to that described in FL-10104.
