Well, I gave it another shot, and I've compiled Net::Pcap, but it does not work (12.50% okay, practically all the tests fail). You'll have to edit Pcap.xs to make the include lines look like 
#include "pcap.h"
#ifdef WIN32
#undef caddr_t
#endif

#include "EXTERN.h"
#include "perl.h"
#include "XSUB.h"
//#include <pcap.h> used to be here (D'oh! i should've just done a dif
+f)

Also, here's what the MakeMaker INC/LIBS args should look like: 
    'INC'          => q[ -IE:\new\wpdpack_3_0\wpdpack\Include ],
    'LIBS'         => [ q[ -LE:\new\wpdpack_3_0\wpdpack\Lib -lwpcap.li
+b ] ],

It compiles with some warnings though 
Pcap.c
Pcap.c(749) : warning C4047: 'function' : 'struct _PerlIO ** ' differs
+ in levels of indirection from 'struct _iobuf *'
Pcap.c(749) : warning C4024: 'Perl_do_open' : different types for form
+al and actual parameter 8

which stem from 
FILE *
pcap_file(p)
    pcap_t *p

and I've no clue how to fix those, but I highly doubt they have anything to do with the failing tests (almost all of the functions Net::Pcap uses are deprecated in WinPcap -- like lookupdev or open_live). The generated function looks like 
XS(XS_Net__Pcap_file); /* prototype to pass -Wmissing-prototypes */
XS(XS_Net__Pcap_file)
{
    dXSARGS;
    if (items != 1)
    Perl_croak(aTHX_ "Usage: Net::Pcap::file(p)");
    {
    pcap_t *    p;
    FILE *    RETVAL;

        if (sv_derived_from(ST(0), "pcap_tPtr")) {
            IV tmp = SvIV((SV*)SvRV(ST(0)));
            p = (pcap_t *) tmp;
        }
        else
            croak("p is not of type pcap_tPtr");

    RETVAL = pcap_file(p);
    ST(0) = sv_newmortal();
    {
        GV *gv = newGVgen("Net::Pcap");
        if ( do_open(gv, "<&", 2, FALSE, 0, 0, RETVAL) )
        sv_setsv(ST(0), sv_bless(newRV((SV*)gv), gv_stashpv("Net::Pcap
+",1)));
        else
        ST(0) = &PL_sv_undef;
    }
    }
    XSRETURN(1);
}

And the typemap specifies FILE * T_IN, and T_IN is 
INPUT
T_IN
    $var = IoIFP(sv_2io($arg))
###################
OUTPUT
T_IN
    {
        GV *gv = newGVgen("$Package");
        if ( do_open(gv, "<&", 2, FALSE, 0, 0, $var) )
        sv_setsv($arg, sv_bless(newRV((SV*)gv), gv_stashpv("$Package",
+1)));
        else
        $arg = &PL_sv_undef;

MJD says you can't just make shit up and expect the computer to know what you mean, retardo!
I run a Win32 PPM repository for perl 5.6x+5.8x. I take requests.
