Moin,

ich beschäftige mich derzeit damit, Redmine zum laufen zu bekommen,
stoße jedoch an einem bestimmten Punkt jedes Mal wieder auf folgenden
Fehler:


Creating config file /etc/redmine/default/database.yml.new with new
version
granting access to database redmine_default for
redmine_default@localhost: success.
verifying access for redmine_default@localhost: success.
creating database redmine_default: success.
verifying database redmine_default exists: success.
dbconfig-common: flushing administrative password

Creating config file /etc/redmine/default/database.yml with new version
NOTE: Gem.source_index is deprecated, use Specification. It will be
removed on or after 2011-11-01.
Gem.source_index called from
/usr/share/redmine/vendor/rails/railties/lib/rails/gem_dependency.rb:21.
rake aborted!
cannot load such file -- active_support

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

Kann da jemand weiterhelfen?

Gruß, Jan
