[Radiant] error after first run after installation

[Grant Morgan]

I am getting this when I first go radiant after installation
ActiveRecord::StatementInvalid in SiteController#show_page

stack trace ends with
/Library/Ruby/Gems/1.8/gems/radiant-0.6.4/vendor/rails/activerecord/lib/active_record/connection_adapters/sqlite_adapter.rb:360:in
`table_structure

I am on OS X 10.5.2
the table exist I can see them in SQLite3 db although I don't what
they should look like.
Rake runs with no errors.
my gem list says
activerecord (1.15.6, 1.15.3)
sqlite3-ruby (1.2.1)
radiant (0.6.4)

ruby -v
ruby 1.8.6 (2007-09-24 patchlevel 111) [universal-darwin9.0]

Any suggestions on what the problem is or where to look?
