The only think pulling libdcmtk2 is piuparts-depends-dummy.

However, shipping /usr/share/dcmtk/dicom.dic in libdcmtk[23] is a violation of
8.2 of the Policy: "If your package contains files whose names do not change
with each change in the library shared object version, you must not put them in
the shared library package."

/usr/share/dcmtk/{dicom,diconde,private}.dic either need to be versioned or
moved into a separate package so that libdcmtk2 and libdcmtk3 are
co-installable.
