[Zope] NEWBIE Q LocalFS Product

[Michael]

I just installed the LocalFS Product on Zope 2.4 and when it initiated, I got 
the following message:

/path/to/zope/Zope-2.4.0-linux2-x86/lib/python/ts_regex.py:87: 
DeprecationWarning: the regex module is deprecated
; please use the re module
  import regex, regsub #, Sync
/path/to/zope/Zope-2.4.0-linux2-x86/lib/python2.1/regsub.py:15: 
Deprecation
Warning: the regsub module is deprecated; please use re.sub()
  DeprecationWarning)  

Is this bad?  Zope still seems to work fine.
