Hey Amit,
   From a quick look at the commit log, I think you've updated Sage, but 
haven't rebuilt the spkgs, of which there are changes in the Sage code 
which require those to be rebuilt. The code on the ticket has nothing to do 
with PARI, so I expect you will experience on "develop" (note, not 
"master") as well. What I'd suggest doing is going into $SAGE_ROOT and 
running "make build". If that doesn't work, there's always the nuclear 
option "make distclean && make".

Best,
Travis
