You might first of all try putting the library in a more accessible 
location.
    bjam --with-regex stage
will copy all the libraries to /usr/local/boost_1_36_0/stage/lib
This shouldn't have any effect on the linker, but it will make the
command lines a bit shorter.

Try adding the option -Wl,--verbose and take a look at the output.
It might provide some hint about the problem.
