Trouble installing Net::Pcap on Win32

[NetWallah]

Greetings, Wise monks - I seek your wisdom, and tolerance for my choice of the Windoze platform for this module. Not being a "c" programmer, many of these dont make sense, so I seek enlightenment. I'm attempting to install Net::Pcap verision 0.04. I have already installed WinPcap, and copied over the development pack. My C compiler is based on Visual Studio Dot Net. This part of the install was successful:

>perl Makefile.PL INC=-IE:\Progra~1\WinPcap\wpdpack\Include  LIBS=-lE:
+\Progra~1WinPcap\wpdpack\Lib -lpcap

However, the next part, running nmake gets these errors:

D:\Download\Programming\Perl\Net-Pcap-0.04>nmake

Stop.

I'm hoping someone will spot something obvious and advise.
