Python UDF for piglatin script cannot find module again

I'm having trouble creating UDF for the piglatin script that I am using. My problem is that when I run the script with pig script.pig, I get the following error:

[main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1121: Python Error. Traceback (most recent call last):
  File "utils.py", line 3, in <module>
    import re
ImportError: No module named re

And in my "utils.py" script, I import the module as follows: import re

Why doesn’t he find the module reand how to fix it?

Edit I should note that if I run the python script directly using the command python, I do not get an error saying that it could not find the module re.

Well, based on the comments, I installed jython (which was not installed on my system) and here are the outputs print sys.pathfor my script:

Using python

['/home/hduser/bqmScripts/betsScripts', '/usr/lib/python2.6', '/usr/lib/python2.6/plat-linux2', '/usr/lib/python2.6/lib-tk', '/usr/lib/python2.6/lib-old', '/usr/lib/python2.6/lib-dynload', '/usr/lib/python2.6/dist-packages', '/usr/lib/python2.6/dist-packages/PIL', '/usr/lib/python2.6/dist-packages/gst-0.10', '/usr/lib/pymodules/python2.6', '/usr/lib/python2.6/dist-packages/gtk-2.0', '/usr/lib/pymodules/python2.6/gtk-2.0', '/usr/local/lib/python2.6/dist-packages']

Using jython

['', '/usr/share/jython/Lib', '/usr/lib/site-python', '__classpath__']

Pig use

['/pig/lib/Lib', '__classpath__', '__pyclasspath__/']

, jython pig, :

 File "utils.py", line 8, in <module>
    import re
  File "/usr/share/jython/Lib/re.py", line 7, in <module>
    import sre, sys
  File "/usr/share/jython/Lib/sre.py", line 97, in <module>
    import sre_compile
  File "/usr/share/jython/Lib/sre_compile.py", line 17, in <module>
    assert _sre.MAGIC == MAGIC, "SRE module mismatch"
AssertionError: SRE module mismatch

, jython, (2.5), . .
