[Simh] Newbie has network compile problem

[Mark Pizzolato]

Hi Steve,

Since you mention libpcap 0.8.1, you've picked a recent version. 
However, it seems not to be being referenced appropriately in your
build.  This could be because it hasn't been installed (by doing the
following as root in the libpcap directory: ./configure; make
install), and/or because the makefile you're using isn't referencing
it appropriately.

Below is the top part of the latest makefile, which should have the
appropriate reference (Be careful that this mailer didn't wrap the
longer lines (i.e. starting with NETWORK_OPT).  Let me know if you
still have problems.
