No module named pylab? about droidbox HOT 5 CLOSED

This is what I got originally:
Traceback (most recent call last):
  File "scripts/droidbox.py", line 30, in <module>
    from pylab import *
ImportError: No module named pylab

Try to modify droidbox.sh and modify it as following:
" adb logcat -c | adb logcat dalvikvm:W *:S | python scripts/droidbox.py $1 "

Hope it will work,
Moutaz

Are pylab and matplotlib libraries installed?

it's ok now

How did you solve the problem?
I am using the Droidbox, and it worked well when I was using Python 2.6, but 
today I changed to 2.7, it stops work, it gives the response:
- waiting for device -
- waiting for device -
Traceback (most recent call last):
  File "scripts/droidbox.py", line 28, in <module>
    from pylab import *
ImportError: No module named pylab

but I have installed matplotlib, so that should works fine, can you tell me how 
did you fix it?
thank you.
PS: I did not change any content of droidbox.sh and startemu.sh, and I am using 
ubuntu 10.04.
