pylab problem after ubuntu update

[esp]

oh boy this is a nightmare .. I ran an update on an ubuuntu machine, and now nothing works ... i re-installed atk, that did not help .. i am not sure what to do ...

Code

  File "/home/patak001//gnr_12_0_AGNR_z10.py", line 335, in <module>
    from parms import *
  File "/home/patak001/parms.py", line 7, in <module>
    import pylab
  File "./build/atkpython/lib/python2.6/site-packages/pylab.py", line 1, in <module>
  File "./build/atkpython/lib/python2.6/site-packages/matplotlib/pylab.py", line 263, in <module>
  File "./build/atkpython/lib/python2.6/site-packages/matplotlib/pyplot.py", line 95, in <module>
