You need to pull BuildSystem.
I'm getting the following after pulling and reconfiguring:
===============================================================================
Configuring PETSc to compile on your
system
===============================================================================
===============================================================================
It appears you do not have valgrind installed on your
system.
We HIGHLY recommend you install it from www.valgrind.org
Or install valgrind-devel or equivalent using your package
manager.
Then rerun
./configure
===============================================================================
TESTING: configureRegression from
PETSc.utilities.Regression(config/PETSc/utilities/Regression.py:32)
