In 1.9, you can use the new rdepof selector:
sudo port clean rdepof:subversion

Pre-1.9, you can use port-rdeps [1]:
./port-rdeps -r subversion | tail -n +2 | sudo xargs port clean

Note that only the dependency that actually didn't finish installing
should need to be cleaned (if you haven't turned autoclean off).
