That's a boost sandbox library that Hartmut and I work on, at times. I had
no idea anybody would try to use it ;-)

Tim, to answer you question, the first problem is that
boost-sandbox/visitor/dynamic_visitor_base.hpp has a bug -- it define
non-inline function. I've just fixed that. But: the plugin library does not
include that header, you must be including it yourself...

As for multiple definition of `(anonymous namespace)::_1', I've no idea
where it comes from. I've tried the testcase you've described and got no
link error. Can you provide:

1. Self-contained example that produces the error (zipped sources)
2. The version of Boost you have (CVS version is recommended)
3. Your compiler

Maybe this will help to fix the problem.
