What makes you think that the INCLUDE_PATH environment variable has any effect?
'man gcc' suggests it does not.

Haven't we been here before? For example, in 

   http://old.nabble.com/Using-boost-library-on-MacOSx-td24645759.html

you ask essentially the same questions. There answer here is the
same as there -- you don't link to the required libraries, and in
this case, it's pretty easy to guess that the required libraries are
called Boost.Thread...

... and Boost.System. And you got exactly the same error about Boost.System
before.

 boost::asio::detail::posix_thread::~posix_thread():blocking_tcp_echo_server.cpp(.text._ZN5boost4asio6detail12posix_threadD1Ev+0x1d):

Add -pthread command line option.

P.S. I suggest you *do not* ask the same question at the same time both on this
mailing list, and on any other web sites. This results in nothing by duplication
of effort.
