All our python3 is suffixed 3 so lilypond can only run with python-2x 
which in the case of the reporter is python-2.7.8
The reporter uploaded the file he has problems with but failed to upload 
file2.ly which is mentioned in testbook.lytex, this file looks well 
written to me. I can't even get to his failure point on my system yet. 
Is there a complete .lytex file somewhere that I can use without copying 
text from the documentation and I also don't understand his comment that 
lilypond-book succeeds "If you place the contents inline, it doesn't 
work; if you include the contents, it works."
