You appear to have a different implementation of the ezmlm contrib installed, than the one you are upgrading to (ie the one that is in smecontribs).
The one in smecontribs is based on Gordon Rowells rpms, the one you have installed (the toaster version) was done by someone else.
They are different packages, so perhaps the "toaster" version needs to be removed before installing the smecontribs one.
