Probleme mit Acidfree 4.7

Hallo zusammen!

Wie bringe ich Acidfree unter Drupal 4.7 zum laufen? Das Modul benötigt das Modul Filemanager das für 4.7 noch nicht zur Vefügung steht. Mit dem CVS Version hab ich eine endlos lange Fehlerliste:

# warning: shell_exec() has been disabled for security reasons in /www/htdocs/w0067f70/modules/acidfree/acidfree.module on line 2160.

Mir als Newbie sagt das überhaupt nichts.
