FontTools alone isn't sufficient. From the Linux (source) download
page at vpython.org:
In support of the 3D text and extrusion objects, you will need to
install the font-handling modules FontTools, ttfquery (version 1.0.4
or later), and Polygon (all available from pypi.python.org), for which
the following conditions apply: "Polygon is being distributed subject
to the following conditions: This distribution contains code from the
GPC Library, and/or code resulting from the use of the GPC Library.
This usage has been authorized by The University of Manchester, on the
understanding that the GPC-related features are used only in the
context of this distribution. It is not permitted to extract the GPC
code from the distribution as the basis for commercial exploitation,
unless a GPC Commercial Use Licence is obtained from The University of
Manchester, contact: http://www.cs.man.ac.uk/~toby/gpc/".
