Not up yet... I'm getting following error with latest download

I get the exact same thing on Mac OS X 10.6.4 Snow Leopard ^

Ok, I think I found a solution.  Someone posted a patch here http://trac.umitproject.org/ticket/328 that seems to work!  Save the following text to "python27patch" or whatever you want, save it in the same directory as the source code, and type: patch > python27patch.  Then just do python setup.py build, pythonsetup.py install, worked for me.

Thanks for posting the info and patch in Comment 6. A tiny correction to the redirection- it should be

  patch < python27patch

Hi,

I can confirm adding the line "#define HAVE_PCAP_FILE" to pcap_ex.c (from pypcap-1.1) solves the error message below. (FWIW: Ubuntu 11.04, python 2.7)

I had to use this patch in addition to the one above, to work with Ubuntu 10.11 (oneiric):
