   When I run bjam from the bjam-problem folder - there is nothing for 
it to do as your Jamroot file does not specify anything to build. Maybe 
that is what you expected it to do, maybe not.

   When I run it from any of the other two folders - everything builds fine.

   I tried this with the current trunk Boost Build using the msvc-9.0 
toolset and the gcc toolset under Cygwin with no INSTALL_PATH 
environment variable set.

   I had to tweak the project files a bit to get it to work in my local 
environment but those changes should not affect you. I'm sending you the 
self-contained projects for both those environments.

   Hope this helps.
