If I were you I'd skip the loop at the top and just run  the
pkg_cutleaves command, delete kde3 and work down through the
new leaf-dependencies.

The loop takes out the first level of  kde3 dependencies, saving you a
few seconds in pkg_cutleaves, but also deletes x11-toolkits/qt33,
which is required by some non-kde apps such as Opera.
