Please tell:

- The exact problem you run into
- What environment you're using
        - Is this GNU/Linux, or MS Windows, or GNU/Kernel32.dll
        - What is line ending of your Boost checkout
- What are the first 10 lines in Boost.Boost output

In short, because trunk tests are using fixed release of Boost.Jam,
hard error is impossible in general.
