I too find that recent versions of Ubuntu offer non-working versions of the
package python-visual, and I don't know why building a new version also
fails. Steve Spicklemire has been doing excellent work in making an easy to
use Linux installer for the new wxPython-based VPython, which is quickly
getting quite mature. Perhaps Steve can post something about the status of
his installer.
