samba - Mar 2013 - Samba 4.0.3 Configure problem

Hi,

I get the following when tring to run ./configure on the source:

Traceback (most recent call last):
  File "./buildtools/bin/waf", line 75, in <module>
    import Scripting
  File "/root/src/samba-4.0.3/buildtools/wafadmin/Scripting.py", line
146
    except Utils.WafError, e:

Any idea what is causing this?
