Not all of the old "monolithic" contribution was transferred to the new "modular" contribution. Some of them can never be carried over. It is up to the community to carry bits of the library that they find useful.
You can try contacting the original maintainer to find out if they plan to move to the new library.
See http://dev.clojure.org/display/doc/Clojure+Contrib for a review of the new contributor and where it all ended.
