Perl-www-curl version 4.17 has an upstream issue that causes the
following error:
curlopt-constants.c:128:49: error: 'CURL_STRICTER' undeclared (first use in this function)
if (strEQ(name, "STRICTER")) return CURL_STRICTER;
This was fixed upstream on the following commit:
https://anonscm.debian.org/cgit/pkg-perl/packages/libwww-curl-perl.git/commit/?id=d83b9f7
Cherry-picking this patch to Alpine.
