You must start Sword Installmgr as root for it to be able to load modules. Start it with these commands:
[me@localhost user]$ su Password: [root@localhost user]# /usr/local/bin/installmgr
You will now see the installmgr window. You will need to use options>local path to point to your local module repository.
Now the available modules will be shown on the left pane and the installed modules on the right. All you need to do is select modules in the left pane and click install to make them available to Sword and BibleTime.
