Thanks for the information. I defined BOOST_ALL_NO_LIB and now I can 
build my module without needing to link in the library. It was actually 
the static library which was being searched for. However there is an 
overzealous need for this library in date_time even when nothing in it 
is being used. There is a bunch of macros for turning off the automatic 
library linking, but finding them on Boost's web page is nearly 
impossible. However I did find BOOST_ALL_NO_LIB.
