One disadvantage (or is it an advantage? I'm never sure) of the fact that portmaster does not maintain state between runs is behavior like you're seeing here. To answer your question, assuming that everything went well with the -o command, there is no reason that portmaster would have to build the port again. The -r option needs an up to date +REQUIRED_BY, which is a side effect of (re)building it; but the above could just as easily be written: portmaster -o www/neon29 www/neon28 portmaster --check-depends portmaster `cat /var/db/pkg/neon29-0.29.3_2/+REQUIRED_BY` I often get the request for this feature (a -r that doesn't rebuild the port) but have never found the time to work on it. I'll try to get around to it soonish. Doug -- Improve the effectiveness of your Internet presence with a domain name makeover! http://SupersetSolutions.com/ Computers are useless.
