Hmm? Well, the matching ones, yes...

I'd not call it ‘worrying’, since it does exactly what it should do, but 
you might want to have a word with 2016 Tobias about how ‘clever’ they 
think they're being.

Us less clever folks will just have to make do with a comment, indeed.

Obcurity by design :-)

Correct. DESTDIR is never the answer (unless, of course, it is).

Now, I think we can pretty safely credit my past self with knowing about 
PREFIX, so I suspect it wasn't as easy as just setting that. Or it's 
used incorrectly to look up data at run time, as some packages are wont 
to do, or something like that. I'll take a look when I get home; with 
extreme luck the problem I was solving there is no longer an issue in 
the current release.

Kind regards,
