With apologies, I didn't at the time (when I was installing some of my ports
with the verbos option) make a note -- it was more of an afterthought, but
in the verbose output of one my 180+ ports I made the past few days, I did
see the hostname show up in the verbose output which made me wonder if this
could be a problem such as if some ports were made which would depend on in
some way the hostname. It may be that there is no problem at all. I'm glad
to learn that Mac OS Forge has successfully cloned and implemented MacPorts
systems for use with multiple machines.

Thanks,

T.M.
