I did get povray 3.7 to compile on the Jessie distro that came with my Pi2. I'll link to another location for the details as this is not 100% about Python. Note however my link to the POV-Ray + Python stuff at my Oregon Curriculum Network website. https://www.raspberrypi.org/forums/viewtopic.php?p=1029037#p1029037 Adrian has written back to say the Github repo for Antiprism (linked from antiprism.com) no longer requires that special CPPFLAGS switch. Just ./configure should do the job (see previously posted Raspbian Recipe). These resources complement the Pi3D library, which is more like VPython (which might compile also?, now that I have boost?). Kirby
