Still, according to luksan/COPYRIGHT, “[s]ubroutines PBUN, PNEW, PVAR,
PSEN” are “for your personal use […] [n]ot for redistribution”.

So my understanding is that we need to remove those four subroutines.
The rest in that directory is LGPLv2.1+.

WDYT?

I don’t see it at
<https://libreplanet.org/wiki/List_of_software_that_does_not_respect_the_Free_System_Distribution_Guidelines>.
Debian has a package: <https://packages.debian.org/source/sid/nlopt>.
Could you check if they apply any patches?

Besides, I suggest reusing the bits about Guile bindings from the patch
I sent.

Thanks,
Ludo’.
