It might be.  What happens if you add

   import python python-extension ;

at the top of your Jamroot?

You need quotes around the path to python, and you either need to double
the backslashes, or simply use forward slashes.

   using python : 2.6 : "C:/Program Files/Python26"

would be correct, although to be frank you probably don't need that line
at all; Boost.Build's autoconfig should take care of it for you.

If that works out for you, try undoing the change I suggested at the
top; the less cruft, the better ;-)

HTH,
