Do you know what version of PyQt you have? Do you have to do anything
special to get this example to work? When I try I get:
hl:/usr/local/share/plplot5.9.3/examples/python$ ./prova.py
Traceback (most recent call last):
File "./prova.py", line 9, in <module>
from qt import *
ImportError: No module named qt
I think this is expected with PyQt4 as I believe the modules were
renamed, i.e. there is no module named "qt" anymore.
