Problem solved and now I want to know how to fix the portfile. But first let me explain the solution. I found this thread: http://lists.macosforge.org/pipermail/macports-users/2007-June/004009.html And changed /Library/LaunchDaemons/org.macports.dhcpd.plist from: <key>ProgramArguments</key> <array> <string>/opt/local/bin/daemondo</string> <string>--label=dhcpd</string> <string>--start-cmd</string> to this: <key>ProgramArguments</key> <array> <string>/opt/local/bin/daemondo</string> <string>--label=dhcpd</string> <string>--restart-netchange</string> <string>--start-cmd</string> Rebooted and that solved the problem. I'm guessing that Mac mini G4 was slower and therefore the race condition was never met and it worked on the older/slower Mac mini. As I rely on dhcpd my question is now how can the portfile be fixed? Brian
