There are some errors in math library:

/home/cc/downloads/boost_1_48_0_beta1/include/boost/math/tools/config.hpp:283:7:

This can be fixed by commenting out lines from 268 to 288. Looks like
preprocessor #if condition on line 264 is incorrect.
Created ticket #6120 for this bug.

Also, there is a regression from previous versions of boost in range library:

/home/cc/downloads/boost_1_48_0_beta1/include/boost/range/iterator_range_core.hpp:
In static member function ‘static IteratorT
boost::iterator_range_detail::iterator_range_impl<IteratorT>::adl_begin(ForwardRange&)

Looks like there must be a const_cast instead of static_cast.
Created ticket #6121 for this bug.

Last error looks like a show-stopper for me.
