Apple deprecated OpenSSL library they have in base system a while 
ago (including MD5 interface), and in 10.9 they additionally 
broke their own version handling framework we've used to silence 
these deprecation warnings.

The warning should go away once you'll compile with non-system 
OpenSSL.  Alternatively, trivial solution is to use:

./configure --with-cc-opt="-Wno-deprecated-declarations"

Previously these warnings was ignored as -Werror wasn't enabled by 
default with clang (http://hg.nginx.org/nginx/rev/c86dd32573c0).
