Fresh download of petsc-lite-3.4.2.tar.gz. Unpack and set PETSC_DIR to the
location

$PETSC_DIR=$PWD ./configure --with-scalar-type=complex

works no problem

$make PETSC_DIR=$PWD all


works no problem (???)

Executes without errors.on python 2.7

On python 3.3, the second line yields
>>> fd = urllib.urlopen("
http://www.mcs.anl.gov/petsc/petsc-dev/include/petscversion.h")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'urlopen'

On python2.7, first line yields

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named requests



On Python3.3, no errors.

Ubuntu repos do not seem to have python requests for 2.7. They just have
python3-requests.


 the default python links to 2.7
