This is quite tricky; we have a lot of packages as we want our students to be able to produce autotools-enabled packages in our tree as easy as possible, so some parts have been moved to macros which are then included. But I very much doubt that's in any way the cause for the issue. I'll post all used macros nonetheless.

I got this fixed. My bad. But all the above still remains.
