dump contact force to vtk file

Hi,
I am trying to dump the contact force to vtk file in order to see the force chain by Paraview. However, it shows no snapshot. I saw that Mark Bentley had coded it. But when I install the EVTK by "python setup.py install", it shows an error as "gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -fPIC -I/usr/lib/pymodules/python2.7/numpy/core/include -I/usr/include/python2.7 -c src/cevtk.c -o build/temp.linux-i686-2.7/src/cevtk.o
src/cevtk.c:4:20: fatal error: Python.h: No such file or directory
compilation terminated.
error: command 'gcc' failed with exit status 1". Does anyone know how to modify it? In addition, is it possible to dump the vtk file instead of intalling EVTK? Thanks.

Hi,
I intall the python2.7 by the code above, but it still has an error shown as "running install_lib
creating /usr/local/lib/python2.7/dist-packages/evtk
error: could not create '/usr/local/lib/python2.7/dist-packages/evtk': Permission denied". I think the python 2.7 is installed. I also installed it by the Ubuntu software center. Does anyone know how to modfiy it? Thanks.
