• Unbreak the build against modern OpenSSL versions and also on 64-bit architectures by using explicit 32-bit int' types instead of long' which length is not constant (machine/compiler-dependent)
• Don't patch and then sed(1)-patch the Makefile, just pass the needed header files and library paths via MAKE_ARGS
• Install documentation in the dedicated DOCS option helper target
• Convert two-line pkg-plist into PLIST_FILES and PORTDOCS
• Provide fallback distfile download locations

Tested on: i386, amd64
