upgraded version of petsc4py

Today I needed to reinstall my PETSc and SLEPc libraries. I did that and those examples seem to work. I believe I now have 3.5 of each. Note: I needed to install SLEPc 3.5 by downloading the tar file instead of using git but that seemed to work ok.

Then I installed petsc4py and slepc4py using pip. I thought that worked ok but then when I tried a simple test case, heat.py, there is a clearly a problem. See below.

It could be that I have my versions mixed up and if that's the case I do apologize for bugging you with this. But if someone could help me to get this straight that would be greatly appreciated.

Thanks,Francis
