In this case, I'm not messing with config files.  It is a problem with
the "stock" install:

1. I have a BlackBerry NDK that puts a version of python.exe in the
PATH, but it is not a full python install (ie no include folder).
2. I have "stock" boost that doesn't build correctly (for Windows, not
just for BlackBerry) because of 1.

So the BBNDK breaks the boost install.

I suspect I should fix the BBNDK to change how it
uses/finds/'installs' python.  But maybe I could also fix how Boost
Build finds python.  In particular, if it is actually looking for
python/include, then make sure the include folder is there beside
python.exe when the exe is found (otherwise keep looking).

Or something like that.

Also, how common is the idea of finding the python install via
python.exe?  ie What else does BBNDK break?
