librocket GUI support

When I run the following program:

from direct.showbase.ShowBase import ShowBase 
from panda3d.rocket import * 

class MyApp(ShowBase): 

    def __init__(self): 
        ShowBase.__init__(self) 

app = MyApp() 
app.run() 

I get this exception:

Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
  File "/usr/share/panda3d/panda3d.py", line 200, in __getattr__
    for obj in dir(self.__manager__.libimport(lib)):
  File "/usr/share/panda3d/panda3d.py", line 129, in libimport
    raise ImportError, message
ImportError: DLL loader cannot find _rocketcore.

This ImportError occurs with both 1.8 and the latest Lucid Lynx buildbot. Like carthartguy, I too have no _rocketcore.so file in /usr/lib/panda3d. Plus this problem occurs both with and without librocket being separately installed on my system. Anyone have any suggestions?
