---------------------------+------------------------------------------------
 Attached patch updates the clojure-contrib port to clojure-contrib 1.2.0.
 Specifically, three changes are made:

 1. +conflicts           clojure-contrib-devel
 2. Fetch strategy was changed from a git pull to a simple http fetch.
 This simplifies port maintenance and corresponds to the official download
 method on clojure.org.
 3. The port installs the binary jar from the distfile instead of building
 from source.
 4. The reference to the version number in the description was removed in
 the interest of "dry" and because it is clearly displayed with "port info
 clojure-contrib".

 Cheers.
