I downloaded 3.12, which seems to do what is expected.

lout file "fontdefs" (from "prv74.lout" line 1):
     1,0: cannot open file fontdefs
lout file "dl" (from "prv74.lout" line 3):
     1,0: cannot open file dl
lout file "C:\programmi\lout\3.24\include\docf" (from "prv74.lout" line 4):
    14,8: extend symbol @BasicSetup not in scope
   14,20: extend symbol @DocumentSetup not in scope
   18,26: fatal error: exiting now


I wasn't able to tweak the @SysInclude's, but, for the sample purpose, I
think, all is needed is:

   @SysInclude { doc }

Also, I deleted:

   @Use { @DocumentLayout @OddLeftMargin { 2.5c @OrIfPlain 0f } }
   @Use { @OrdinaryLayout }

This way, it works with Lout 3.24.

Ciao.
