Under Linux, you can just point simh at the raw CD drive (/dev/cdrom
or whatever its device point is), and it will happily use it. You can't do
this under Windows.

Is libpcap installed in /usr/lib or /usr/local/lib?
You will need to modify the makefile if you intalled it
into /usr/local/lib. Search for 'pcap', and the change should
be fairly obvious.

I've run it under Linux without any problems.
You may want to try the version without networking
first, to figure out the easier parts.
