[Radiant] Import/Export Extension

[Brian Gernhardt]

I'm attempting to set up a test install of radiant with the data from  
my live site.  I did the following steps:

----------
   git clone git://github.com/seancribbs/radiant.git
   radiant/radiant/bin/radiant test
   cd test/vendor
   ln -s ../../radiant/radiant .
   cd extensions
   ln -s ../../radiant/extensions/import_export .
   cd ../.. # test directory
   rake db:import TEMPLATE=../site-export.yml
----------

Where site-export.yml is a saved copy of the /admin/export page from  
my site (running 0.6.4 gem)

Instead of the wonderfully easy import I had hoped for, I get:

----------
   (in /Users/brian/dev/silver/radiant)
   rake aborted!
   Don't know how to build task 'db:import'

   (See full trace by running task with --trace)
----------

"rake -T" does not include the db:import and db:export tasks, either.   
It does include the tasks from the archive and markdown_filter  
extensions (from radiant.git/radiant/vendor/extensions/).

Have I missed something important, or is the import_export extension  
broken?
