I don't see it as a buildbot-specific issue. The buildbot just builds ports. The problem is that the replaced_by keyword only deals with upgrades. MacPorts base needs to be enhanced so that replaced_by also prevents installations, and does so in a way that displays the message to the user but does not consider this to be a failure.

Same with ports that are not compatible with certain versions of OS X. MacPorts base has no keyword to indicate that, so each port implements it manually with a pre-configure error message. There have been some proposals, including modifying the "platforms" keyword to accept versions.
