I've tried everything I could think of to get it installed. But It keeps giving me the same error.

I suggest you to install python 2.5 (i think you can have both 2.5 and 2.6).
Then you can simple download and install the binary package o pcapy from here.

Ofcourse you must have winpcap already downloaded.. here is the link

I'd rather have 2.5 as a last resort. I'd like to compile it myself.
I have winPcap.
It works great with wireshark and microsoft's network monitor.

Be aware that Python25 and Python26 use different MS C compilers and so do the modules they use. The C code syntax has to match these compilers, as they are not compatible.
