I downloaded ckeditor and unpacked it. I then transfered the file to /usr/share/drupal6/sites/all/modules/ .
Why wont the editor show up on the site building>modules page. I did exactly the same thing with WYSIWIG, OpenWYSIWYG  and Whizzywig with no problems.

This is a Debian Squeeze installation with Drupal 6, manually assembled. (No use of drupal loaders).

Any help will be appreciated.
