In a perfect macports world, port dependents freetype is enough to guess
which ports may need rebuilding, and this script is not necessary.

For a first guess whether rebuilding will be necessary, you can have a
look at which number libfreetype.*.dylib gets. 2.1.10 as well as 2.3.2
define a libfreetype.6.dylib, so there should not be breakage that a
rebuild may solve: if there was a change, the dependents should not
compile.

find /opt/local/var/db/dports/software/ -name "libfreetype.?.dylib"
should show you which number the libfreetype has in the different
releases you have installed (including the old one).
