Sorry it took so long to come up with an answer, Paul. It was staring
me right in the face the whole time, though:

You just need to make sure your PYTHON_INCLUDES variable has two
elements. Depending on how your shell treats quotes, that could take
several forms. The shells I have available, e.g. bash, will let you
embed a space in a command-line argument as follows:

bjam -sPYTHON_INCLUDES="/afs/.slac.stanford.edu/package/python/common/2.0/include /afs/.slac.stanford.edu/package/python/sun4x_55/2.0/include" ...

And bjam splits up variable values on whitespace boundaries.

Some shells let you set up variables with embedded spaces in the
environment; you might try that if your shell doesn't cooperate when
you try to use quotes in the command-line.
