thanks. I will add in runitime-link=static and see if that gets it to compile.

It looks like the patch has already been done.   https://svn.boost.org/trac/boost/ticket/5053

NOTE: putting -static in one of the cflags variables for all of boost allows program_options to compile, but breaks other libs.

How would you set it up so that -static is passed to just program_options or even just parsers.cpp? Is that possible?

Is there an entry I can put into user-config.jam that instructs bjam to pass in an extra flag when compiling parsers.cpp?  I've been going through the documentation, but I'm not exactly sure what I'm looking for. I'd appreciate some guidance.
