I've done the following:

# This erases content of lexical_cast.hpp,
# invokes b2 headers and outputs size of lexical_cast in boost/ folder
echo "">libs/conversion/include/boost/lexical_cast.hpp; ./b2 headers; ls
-ls boost/ | grep lexical_cast.hpp

Output (size is ~11KB):
100 -rw-rw-r-- 1 apolukhin apolukhin 101879 Mar  5 14:48 lexical_cast.hpp

While the following:
ls -la libs/conversion/include/boost/ | grep lexical

Outputs (size is 1 byte):
-rw-rw-r-- 1 apolukhin apolukhin    1 Mar  5 15:40 lexical_cast.hpp

Looks like something is wrong...
