A barest hint: I heard the trick is to get socket.c to compile under NextOS. Perhaps all that's involved is changing a few of the #include lines? Be sure and start with the latest CLX, available via public ftp from export.lcs.mit.edu in the contrib directory. I'm not a C hacker, so this is pretty much all I know, if not a bit more. good luck, -f PS Lemme know how it goes.
