Hi all,
I am trying to run gnfs code from this link 
(http://wstein.org/wiki/ant07%282f%29projects%282f%29shumow_raw.html) in 
sage. I am getting following error;






















*AttributeError                            Traceback (most recent call

(build/cythonized/sage/structure/misc.c:1775)()AttributeError: 
'Ideal_principal' object has no attribute 'quo_rem'*

I never had this problem with the previous installation. Unfortunately due 
to my OS crashing, I had to install it all over again. So far, I have 
installed two versions i.e. 6.4 and 6.3. both are giving the same error. 
Please suggest some way out.
Thanks
Anil
