can you try to explicitly specify the full name of the source file, 
including the suffix you'd like to use:

    env.Substfile(dest='bar', source='foo.argh', SUBST_DICT = dict)

? Does it work then (it should actually)?

Best regards,

Dirk

Yes they do, and it is set to '.in' for the Substfile Builder. This 
means that whenever you don't enter a suffix for your source, it gets an 
'.in' appended. If you provide a complete filename (either target or 
source), SCons relies on your input and doesn't try to decorate it with 
prefixes and suffixes any further...
