Yes, sorry. I didn't have my VM running so couldn't do a build. There's 
an example at the end of this post. Again, just re-running the build 
command cleared it up. It seems to do some extraneous copies into the 
install location, but I'm not too bothered about that -- it doesn't 
appear to do any harm.

I'm d/ling trunk now. Will build bjam from there and try that.

Thanks Vladimir
