Having Sed Error - Building Wireshark

["Pavlu, TJ" <tpavlu () mitre org>]

I am on a windows XP machine and I am trying to build the wireshark source so I can start making dissectors. I keep 
getting a variety of errors. I first off am getting a sed error saying s is an unknown operation.
I tried replacing all the / in the sed commands with # and then it would move farther in the build but I later 
encountered errors that are making me think that this didn't work 100%.
I was wondering If someone could explain why this sed error is occurring and how to rectify it.

This is what I get for my tool verification.

Checking for required applications:
        cl: /cygdrive/c/Program Files/Microsoft Visual Studio 9.0/VC/BIN/cl
        link: /cygdrive/c/Program Files/Microsoft Visual Studio 9.0/VC/BIN/link
        nmake: /cygdrive/c/Program Files/Microsoft Visual Studio 9.0/VC/BIN/nmake
        mt: /cygdrive/c/Program Files/Microsoft SDKs/Windows/v6.0A/bin/mt
        bash: /usr/bin/bash
        bison: /usr/bin/bison
        flex: /usr/bin/flex
        env: /usr/bin/env
        grep: /usr/bin/grep
        /usr/bin/find: /usr/bin/find
        perl: /usr/bin/perl
        C:\Python26\python.exe: /cygdrive/c/Python26/python.exe
        sed: /usr/bin/sed
        unzip: /usr/bin/unzip
        wget: /usr/bin/wget

Does this look right and also how do I change where my mt is pointing because I believe that is also wrong but One 
thing at a time.
