It is better to use the debian-octave mailing list for this kind of 
discussion.

Actually, the patch d/p/octave4.4.patch, created by Sébastien was 
intended to fix the problem above.

Indeed, the version of nlopt current in Git (@Salsa.d.o) builds 
correctly for me in a clean sid chroot with octave 4.4.0-3.  Could you 
please send your build log to us?

Cheers,
