First, and again. Ruby is very picky about compilers and its version.

You should use exactly the same version of the compiler that was used
to create that Ruby binary.

If you're using either garbagecollect downloads or One-Click
Installer, then you need Visual C 6.0

That can't be sent, shared or adquired, since is 12 years old
compiler.

Please, again, try the above indicated instructions about getting
RubyInstaller and the Development Kit.

Once you have that setup, you can workout all the other details.

Help us help you, you actually don't provide the real information we
need. For example, you mention "It can find pcap.h which I have told
the tools to search for include files"

How you did that? We don't look for narrative text, we want facts and
screen output, actual error messages and environment variables.

Is RubyInstaller AND the DevKit.

Also, when reporting issues, again, try to provide all the information
relevant to your environment:

Ruby version (ruby -v)
RubyGems environment info (gem env)
Your PATH (set PATH)
Your OS and configuration (which flavor of Windows, 32 or 64 bits,
etc.)

Complete output of the error you're receiving. If is long, use a paste
service like Pastie or Gist (GitHub) (if you have an account).

Also, if you can provide the sample script that generated the issue,
the better.

Again, help us help you.
