Additional context

Had this problem and these changes actually made it work properly.

[danny-smit]

Had the problem as well, this fixed it mostly. I only had to add the following change to remove the "Recursive requisite found" message for the configure modules:

Small update to my previous comment.

The state in apache/config/modules/install.sls contains a hard order: 225, which would order it before all other states without an order key. This can give problems on new installed machines. Instead, the following change should fix both the "Recursive requisite" and the ordering issue:
