[GtkGLExt] PyGtkGLExt 1.1.0 installation on ubuntu edgy

[dario oddenino <dariooddenino fastwebnet it>]

Hi everyone, it's the first time I use a mailing list, so I hope I'm not
doing anything wrong!
The problem is that I can't install pygtkglext
when I run the command 
$ python setup.py install

I get this error

Traceback (most recent call last):
  File "setup.py", line 117, in ?
    override='gtk/gdkgl/gdkglext.override')
  File "/var/lib/python-support/python2.4/gtk-2.0/dsextras.py", line
415, in __init__
    kwargs['register'], load_types))
  File "/var/lib/python-support/python2.4/gtk-2.0/dsextras.py", line

    raise NameError("'%s' is not defined\n" % cls.__name__
NameError: 'Template' is not defined

***************************************************************************
Codegen could not be found on your system and is required by the
dsextras.Template and dsextras.TemplateExtension classes. codegen is
part
of PyGTK. To use either Template or TemplateExtension, you should also
install PyGTK.

PyGTK is installed and works correctly
Thank you for answers!
