Really? The SCons search path for executables when initialising tools
should be different from the SCons search path when trying to execute
the tools executable. This I do not believe. Yet this is what SCons
does. :-(

As I understand it on Darwin those files are always processed to create
a search path.  Why is SCons not just saying "OK OS give me your
standard search path" – for all platforms. Why is SCons assuming it
knows better than the platform what the platform's standard search path
is?

DMD is being found on my system at tool set up time, but not at tool
executable execution time.
