I am trying to install PyOp2 on my Macbook (10.9) and I'm having an issue. In my terminal, I typed:

wget -O - https://github.com/OP2/PyOP2/raw/master/install.sh | sudo bash

and at the end of my install log file:

"Successfully installed petsc4py

Cleaning up...

*** Installing PyOP2 ***

Cloning into 'PyOP2'...

Checking connectivity... done 

Traceback (most recent call last):

  File "setup.py", line 45, in <module>

    import petsc4py

ImportError: No module named petsc4py"

Sincerely,

Brian
