Sometimes when port versions are updated, that causes bugs to be fixed. We don't want you to experience those bugs, nor do we want to spend time dealing with bug reports from users for bugs that are already fixed.
Sometimes ports change in ways other than just the version of the upstream software, and you don't have any visibility to such changes just by looking at the output of "port outdated". You know, for example, that ncurses was updated, but you don't know why. Part of the point of MacPorts is for you to be able to install software without having to know all about the intricacies of the dependencies or issues they might contain. To a certain extent, you have to trust us that when we make an update available to you, you should install it.
The order of installation of such updates is significant. You should not circumvent the upgrading of dependencies (using "-n") because that may in some cases defeat the purpose for the update.

>> MacPorts has always first upgraded dependencies of the ports you asked to install or upgrade. Not doing so would be completely counterproductive to the way that MacPorts is designed to work. We will not help you attempt to circumvent a fundamental functionality of MacPorts, because it would likely increase our support burden when you do this and then ask us why things aren't working right.

I assume from your answer that there is no intention whatsoever of implementing a >= check for dependencies versions. It doesn't sound so unreasonable to me, but then again I'm not the one developing it…
MacPorts does not have the capability to declare a dependency on a specific version of a dependency, nor does MacPorts have the capability to install an arbitrary version of a dependency. It's always only the version currently available in MacPorts.

MacPorts has pre-built binaries now. This does not cover all ports, all systems, or all variants, but it does cover many. If you are on Snow Leopard, Lion, or Mountain Lion; on x86_64; using default prefix, applications_dir and frameworks_dir; and using default variants; then MacPorts should be downloading and using pre-built binaries instead of building from source.
