That was the first thing that came to mind. But there isn't any occurrence
of bio_molecular.H with uppercase H in my source files:

biopp/$ grep -R bio_molecular.H *
biopp/$ grep -R "bio_molecular\.H" *
biopp/$ grep -R "bio_molecular\.h" *
biopp/bio_molecular/exceptions.h:    bio_molecular.h: Molecular Biology ++
Header file.
biopp/bio_molecular/bio_molecular.h:    bio_molecular.h: Molecular Biology
++ Header file.
biopp/bio_molecular/definitions.h:    bio_molecular.h: Molecular Biology ++
Header file.
biopp/biopp.h: #include "biopp/bio_molecular/bio_molecular.h"
tools/generate_graph.cpp:#include "biopp/bio_molecular/bio_molecular.h"

I'm not saying that the issue is with scons proper, I'm sure I'm messing
something somewhere. But I need to understand where this process (the
implicit dependency search) is taking place so I can trace where the file
name is getting mangled.
It puzzles me that the astyle subprocess is being run and the "error" is
rising afterwards.
