You appear to lack the WinPcap developer pack.

If it is installed in a non-standard location, please try setting the LIBS
and INC values on the command line.  For instance, if you have unziped the
developer's pack in C:\WpdPack, you should execute:

    perl Makefile.PL INC=-IC:/WpdPack/Include "LIBS=-LC:/WpdPack/Lib -lwpcap"

Or get and install the WinPcap developer's pack from
  http://www.winpcap.org/install/
