graphvizをアップグレードしようと思ったら…，
before
$ sudo port upgrade graphviz
- > Activating xorg-renderproto @0.9.3_0
Error: Target org.macports.activate returned: Image error: /opt/local/include/X11/extensions/render.h is being used by the active render port. Please deactivate this port first, or use 'port -f activate xorg-renderproto' to force the activation.
Error: The following dependencies failed to build: xorg-renderproto
Error: Unable to upgrade port: 1
- > Extracting graphviz
Error: On Mac OS X 10.5, graphviz 2.22.2 requires Xcode 3.1.2 or later but you have Xcode 3.0.
Error: Target org.macports.extract returned: incompatible Xcode version
Error: Unable to upgrade port: 1
Xcodeをバージョンアップしないといけないようです。
ということで，以下を参考にXcodeをバージョンアップしました。ファイルサイズは，995.8MBでした。
after
$ sudo port -f activate xorg-renderproto
$ sudo port upgrade graphviz
