Apple stopped shipping the openssl headers a year or two back.  (The
copies you see must be from back-rev SDKs; there are none on my laptop.)
It looks like they still provide the shared library, but it's pretty
useless if you can't compile new source against it, and it also looks

$ ls -l /usr/lib/*ssl*
-rwxr-xr-x  1 root  wheel  400608 Sep  9  2014 /usr/lib/libssl.0.9.7.dylib*
-rwxr-xr-x  1 root  wheel  616560 Aug  5  2015 /usr/lib/libssl.0.9.8.dylib*
lrwxr-xr-x  1 root  wheel      18 Oct 18  2014 /usr/lib/libssl.dylib@ -> 

Personally I just install openssl from source into /usr/local and then
build/link against that.
