Right, that's a minor version update. If the libsdl developers are following sensible version numbering practices, 1.2.15 should be fully backward-compatible with 1.2.14. Let's have a look:

$ port -q installed libsdl
  libsdl @1.2.14_9+universal+x11 (active)
$ otool -L /opt/local/lib/libSDL.dylib | head -n 2
/opt/local/lib/libSDL.dylib:
	/opt/local/lib/libSDL-1.2.0.dylib (compatibility version 12.0.0, current version 12.3.0)
$ sudo port -u upgrade libsdl

$ port -q installed libsdl
  libsdl @1.2.15_0+universal+x11 (active)
$ otool -L /opt/local/lib/libSDL.dylib | head -n 2
/opt/local/lib/libSDL.dylib:
	/opt/local/lib/libSDL-1.2.0.dylib (compatibility version 12.0.0, current version 12.4.0)

As you see, the compatibility version is the same, so no revbump is needed. Now, if libsdl had been updated to 1.3, the library version probably would have changed, since 1.3 has been in development forever and we already know it's drastically different from the 1.2 series, so that would indeed have required a revbump of all ports using it.
