Well aside from the default bjam flags being wrong for making shared  
libraries on OS X (-shared is not valid), some interesting things  
happen, like this:

(lots more stuff was up here)
/usr/include/gcc/darwin/3.3/c++/bits/stl_multimap.h:165:   instantiated  
from `std::multimap<_Key, _Tp, _Compare, _Alloc>::multimap(const  
_Compare&, typename std::_Rb_tree<_Key, std::pair<const _Key, _Tp>,  
std::_Select1st<std::pair<const _Key, _Tp> >, _Compare,  
_Alloc>::allocator_type&) [with _Key = boost::any, _Tp =  
boost::signals::detail::connection_slot_pair, _Compare =  
boost::function2<bool, boost::any, boost::any,  
std::allocator<boost::function_base> >, _Alloc =  
std::allocator<std::pair<const boost::any,  
boost::signals::detail::connection_slot_pair> >]'
libs/signals/src/signal_base.cpp:27:   instantiated from here
/Users/bob/src/Python/boost/boost/function/function_template.hpp:391:

Lots of this:

/Users/bob/src/Python/boost/boost/python/converter/ 
rvalue_from_python_data.hpp:100: sorry, unimplemented: `
    tree_list' not supported by dump_expr

with this at the end:

...failed updating 87 targets...
...skipped 24 targets...

Probably because -shared is not how to make dynamic libraries on OS X,  
but I'm not sure.  I can't really put a lot of time into trying to get  
this to work, but it looks pretty hopeless with this version of gcc due  
to the internal compiler error.  Perhaps a newer version of XCode may  
not have this problem?
