I'm the one who worked out much of the porting details for the
current networking support.

The above advise is not currently correct.

There is documentation on how to build with networking support on all
Unix/Unix-like platforms included in the current release.  Please
read 0readme_ethernet.txt carefully.

Get back to me with furthur questions.
