net/ldns fails to compile on Mac OS X 10.5.6 with the following error during 
configure:

checking for SSL... found in /usr
checking for HMAC_CTX_init in -lcrypto... yes
checking for openssl/ssl.h... yes
checking for openssl/err.h... yes
checking for openssl/rand.h... yes
checking for SHA256 and SHA512... checking for SHA256_Init in -lcrypto... no
configure: error: SHA2 enabled, but no SHA2 functions found in OpenSSL

>How-To-Repeat:

>Fix:
The builtin OpenSSL on Mac OS X doesn't seem to support SHA256.
