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’.
