[Insight-users] building ITK with Python wrappers on Ubuntu 13.04

[Young Lee]

Hi,

I was wondering if anyone had any suggestions on the error I'm getting 
when I try to build ITK 4.4.0 with Python wrappers on Ubuntu 13.04.  I'm 
able to build it OK on RHEL 6.2 and Ubuntu 12.04.  I can also build 
ITK4.4.0  on Ubntu 13.04 without problems if I turn off the Python 
wrappers option.  But when I try to build ITK4.4.0 with Python wrappers 
on Ubuntu 13.04,  I get the following error message:
