Freezing to 1.2.6 appears to be broken right now for two reasons. My environment is using rails 1.2.6 and rubygems 0.9.5 Attempting to freeze to 1.2.6 with this will result in this output & error:
% rake rails:freeze:edge TAG=rel_1-2-6 ... ** Invoke rails:freeze:edge (first_time) ** Execute rails:freeze:edge A vendor/rails/railties
. . .
A vendor/rails/activesupport/MIT-LICENSE A vendor/rails/activesupport/README Exported revision 8214. svn: URL 'http://dev.rubyonrails.org/svn/rails/tags/rel_1-2-6/ activeresource' doesn't exist
To fix this, you need to edit the .../PATH_TO_RAILS/lib/tasks/ framework.rake file and remove activeresource from the for loop here:
