Different:
   File "/usr/lib/textbook/prtempl/prn_ascii.py", line 23, in ?
     import time
ImportError: /usr/local/lib/python2.2/lib-dynload/time.so: undefined

My port on SCO still uses 1.4
Is there any way to make my code use regsub module on 1.4 and re module 
on 2.2 without branching? I could not kill SCO port just yet and would 
rather not go thru the trouble of upgrading it to 2.2

re.sub() works like charm. Thank you.
