This means some directory has both project-root.jam and Jamroot. 'project-root.jam' is old 
spelling, and Jamroot is new, and Boost.Build naturally cannot load both. Are you sure 
you're not unpacking 1.37 over some old tree? 

I have committed a fix to improve this error message, like so: 

        error: Multiple Jamfiles found at '.' 
        error: Filenames are: Jamroot jamroot.jam 

- Volodya 

That is EXACTLY what I was doing.... I'm checking the source into our own repository so our devs can always check it out and build it and I simply copied 1.37 over 1.35. Thanks Volodya.

The improved error messages will help, but since we mostly use old school style perforce jam files I doubt I would have figured it out. (Though someone else less clueless than I might have)
