Errors compiling boost example of ssl client - c++

Question

I'm trying to compile the boost example from http://www.boost.org/doc/libs/1_47_0/doc/html/boost_asio/example/ssl/client.cpp . For some reason I'm getting the following errors and I don't know how to fix them:
ssl_client.cpp:37:25: error: ‘boost::asio::ssl::verify_context’ has not been declared
ssl_client.cpp: In constructor ‘client::client(boost::asio::io_service&, boost::asio::ssl::context&, boost::asio::ip::basic_resolver<boost::asio::ip::tcp>::iterator)’:

I'm currently compiling with the following line:
g++ -I /usr/include/boost -Wall -o main ssl_client.cpp -lboost_system
And I recently installed boost through:
sudo apt-get install libboost-all-dev
I'm sure there's an easy fix, does anyone know what I'm doing wrong?
========================================================================
Update:
I've now tried compiling with:
g++ -I /usr/include/boost -Wall -o main ssl_client.cpp -lboost_system -lcrypto -lssl -lpthread
but I'm still getting the following errors:
ssl_client.cpp:37:25: error: ‘boost::asio::ssl::verify_context’ has not been declared

Fixed it! It was because apt-get was giving me boost version 1.46 and I needed version 1.48. I did the following to fix it:
apt-get purge libboost-all-dev
and
apt-get install libboost1.48-all-dev
