[oe] Bitbake build error on Fedora 12 x86 64-bit

[Elvis Dowson]

Hi,
                  I get the following error when attempting to build overo on Fedora 12 x86 64-bit version. 

Can you tell me how you can resolve this?

bitbake omap3-console-image

Traceback (most recent call last):
  File "/tool/overo-oe/bitbake/bin/bitbake", line 143, in <module>
    main()
  File "/tool/overo-oe/bitbake/bin/bitbake", line 123, in main
    cooker.parseConfiguration()
  File "/tool/overo-oe/bitbake/lib/bb/cooker.py", line 68, in parseConfiguration
    self.parseConfigurationFile( os.path.join( "conf", "bitbake.conf" ) )
  File "/tool/overo-oe/bitbake/lib/bb/cooker.py", line 404, in parseConfigurationFile
    bb.event.fire(bb.event.ConfigParsed(self.configuration.data))
  File "/tool/overo-oe/bitbake/lib/bb/event.py", line 67, in fire
    if tmpHandler(event) == Handled:
  File "tmpHandler(e)", line 4, in tmpHandler

NameError: global name 'os' is not defined
