LD_LIBRARY_PATH not found

[Yaio]

Ubuntu 10.10 32 bit / daily build
If I launch a packp3d command I receive this error:

$ python /usr/share/panda3d/direct/p3d/packp3d.py -o example.p3d
Traceback (most recent call last):
  File "/usr/share/panda3d/direct/p3d/packp3d.py", line 219, in <module>
    makePackedApp(sys.argv[1:])

    packager = Packager.Packager()

KeyError: 'LD_LIBRARY_PATH'

I committed a fix. As a workaround, you can just set the LD_LIBRARY_PATH environment variable to the empty string before running packp3d.
