[oe] what is "No module named pstats"?

[E Robertson]

Hi,
I I go this error during the stage build it is always and only during
the stage. so I use this comand "bitbake -vP -b touch257 -c stage.
My stage routing in the bb file is ok just like any other.
Do I need to add this to any other file to complete the last phase?

NOTE: package touch257-2.0.8.0: started
ERROR: InvalidTask event exception, aborting
NOTE: package touch257-2.0.8.0: failed
ERROR: Build of 'touch257' failed
Traceback (most recent call last):
  File "/usr/bin/bitbake", line 134, in <module>
    main()
  File "/usr/bin/bitbake", line 123, in main
    import pstats
ImportError: No module named pstats


Thanks.
