Alright, Glynn's answer explained this (some Ubuntu stupidity),
so no need to worry about it any further.

Python 2.5.1 and wxPython 2.8.4.

Further tests:

The interactive setting and editing of GCPs works and so does
calculation of RMS -- although I find it confusing that an old marker does
not get deleted from the display when I re-place it somewhere else. Would an
automatic screen redraw be feasible?

Anyhow, pressing the "Georectify" icon just dumps this to the console:

Traceback (most recent call last):
  File "/usr/local/grass-6.3.svn/etc/wxpython/gui_modules/ge
orect.py", line 825, in OnGeorect

self.SaveGCPs()
TypeError
:
SaveGCPs() takes exactly 2 arguments (1 given)



Is there a minimum of 3 GCPs that have to be set? If so, the user should
be advised about this when trying to use less than 3. In theory, one
or two GCPs could also be useful for cases where only a linear translation/
/scaling/rotation is needed.

Have a good conference.

Best,

Benjamin
