We're busy fixing compiler and platform specific issues, in preparation for 
a 1.35 release.  BTW that means that the version in SVN Trunk has *slightly* 
more fixes in it than the sandbox version - which will be used for ongoing 
development.

I don't know, it works OK with Sun 5.9 on Linux (the only version of the sun 
compiler I have access to), and the definition for that function is 
certainly present in the header.

It's not helped by the Sun regression tests being stalled for the last 
couple of weeks either :-(

The function is defined like this:

template <>
inline int 
digits<concepts::real_concept>(BOOST_MATH_EXPLICIT_TEMPLATE_TYPE_SPEC(concepts::real_concept))
{
   return tools::digits<long double>();
}

Does this ring any bells as something that's problematic on that compiler? 
How about if the inline specifier is removed?

HTH, John.
