This is a known bug, that as far as I know doesn't have a solution 
(yet). When compiling with optimization, darwin gcc doesn't seem to 
complete. Because it works without the -O flag, it is believed to be a 
bug with the compiler, and a bug report has been submitted to apple.

On my machine, I went into xml_grammar.cpp (and xml_wgrammar.cpp). Down 
near the bottom there is an explicit instantiation of a template. I put:
#ifndef NDEBUG
template class basic_xml_grammar<char>;
#endif //NDEBUG
This at least lets the compile finish. It probably means that if you 
link against the release version of the library, you will get missing 
symbols, but since I don't use the serialization library yet, it works 
for me.

There is probably some way of fixing the Jamfile that prevents it from 
setting the optimization flag, maybe
<darwin><*><optimization>off
Or something like that, I didn't try.
