[sugar] goocanvas import error!

[Shankar Pokharel]

Gonzalo has already asked this question previously but Marco's answer
is related to jhbuild only. I was just now trying to run sugar on
Ubuntu 6.06 after I installed from the source. I got this error.

======================================
Running the installed sugar...
Traceback (most recent call last):
  File "/usr/local/bin/sugar", line 29, in ?
    from session.Session import Session
  File "/usr/local/share/sugar/shell/session/Session.py", line 7, in ?
    from Shell import Shell
  File "/usr/local/share/sugar/shell/Shell.py", line 10, in ?
    from home.HomeWindow import HomeWindow
  File "/usr/local/share/sugar/shell/home/HomeWindow.py", line 3, in ?
    from home.MeshView import MeshView
  File "/usr/local/share/sugar/shell/home/MeshView.py", line 3, in ?
    import goocanvas
ImportError: No module named goocanvas
====================================================

As I can not build from jhbuild due to my ISP's proxy problems, please
suggest me what to do?

Shankar
