Hi again,

the missing bit is the definition of the 'TARGET', 'SOURCE' etc.
variables that are required for env.subst() to work. I'm still not sure
where this is done inside SCons, and what the supposed way is to hook
this up with the execution of custom python functions.

However, what appears to work fine is to call

    env.subst('$TARGET', target=<the-target>)

The documentation at
http://scons.org/doc/production/HTML/scons-user/ch07s02.html#idp1400500516
is missing this important point.



Thanks,
        Stefan
