I've uploaded a new version and added the BOOST_ON_BLOCK_EXIT macro. (Is there a way to get the BOOST_JOIN macro without including all of config.hpp?)

I've never needed the Janitor class, so didn't include it. If you've needed it, let's put it in.
In a private e-mail Andrei expressed regret about the catch(...) in the destructor. I've added an "exception action" argument to be invoked when the users function throws. By default it swallows the exception (as ScopeGuard), but it can easily be configured to propagate the exception. In the tests is also an example of translating an exception.
