boost/asio/ssl throwing "undefined reference" error - c++

Question

I am new to boost and am trying to compile the most basic program that includes boost/asio/ssl.
I am working on ubuntu 13.10 64bit and installed the latest boost like this:
sudo apt-get install boost-all-dev
Here is the magnificent code I am trying to compile:
#include <stdio.h>
#include <boost/asio/ssl/stream.hpp>
int main(){
printf("Hi\n");
return 0;
}
I googled and googled and the few hints I was able to find suggests I use some boost library flags. So I did:
g++ my_prog.cpp -o my_prog.bin -lboost_system -lboost_thread -lpthread
and all the time I get the same error message (no matter how many -l i shove in):

collect2: error: ld returned 1 exit status
Or in short: it complaining about missing symbols like:
undefined reference to `SSL_library_init'
or:
undefined reference to `ERR_reason_error_string'.
Another funny fact is that if I change the include:
#include <boost/asio/ssl/stream.hpp>
for example to
#include <boost/asio/ssl/stream_base.hpp>
it compiles just fine (even without -lboost_system and all others..).
I spent a whole day on this and still can't for the life of me figure this out.
Any ideas guys?

In vs2013, when I include <boost/asio/ssl.hpp> I see
unresolved external symbol _CONF_modules_upload
unresolved external symbol _ERR_reason_error_string
I solved those issues by adding
libcrypto32MD.lib
in Linker/Additional Dependencies
