As I suggested right at the outset you need to make up your own stylesheet 
following the model in say standard.py

I did the following


1) copy standard.py to madness.py in the styles subfolder
2) edit styles/madness.py
    replaced all instances of Times-Roman with LettErrorRobot-Chrome
    added some registration stuff at the beginning of the function

def getParagraphStyles():
	"""Returns a dictionary of styles to get you started.

	We will provide a way to specify a module of these.  Note that
	this just includes TableStyles as well as ParagraphStyles for any
	tables you wish to use.
	"""
	
	# this is added
	from reportlab.pdfbase import pdfmetrics
	pdfmetrics.findFontAndRegister('LettErrorRobot-Chrome')
	pdfmetrics.registerFontFamily('LettErrorRobot-Chrome')
	################

	stylesheet = {}
	ParagraphStyle = styles.ParagraphStyle

	para = ParagraphStyle('Normal', None)	#the ancestor of all
	para.fontName = 'LettErrorRobot-Chrome'

3) copy pythonpoint.xml to madpythonpoint.xml
4) changed standard in the <stylesheet tag to be madness in madpythonpoint.xml
5) run pythonpoint.py on the madpythonpoint.xml
6) open madpythonpoint.pdf and admire my foolishness
