Hash: SHA512

GnuPG 2.1.3 has introduced a hard dependency on LDAP, resulting in
failure if openldap is not present despite being configured with
- --without-ldap. Full build log at [0], but the relevant snippet is

/lib\""               -O2 -pipe -Wall -Wno-pointer-sign
- -Wpointer-arith -c -o ldap-parse-uri.o ldap-parse-uri.c
ks-engine-ldap.c:43:19: fatal error: ldap.h: No such file or directory
 # include <ldap.h>
                   ^
compilation terminated.
Makefile:755: recipe for target 'ks-engine-ldap.o' failed
make[3]: *** [ks-engine-ldap.o] Error 1
make[3]: *** Waiting for unfinished jobs....
ldap-parse-uri.c:27:19: fatal error: ldap.h: No such file or directory
 # include <ldap.h>

missing some USE_LDAP enclosures?
