Hi,

I have it too, in a private repo.  :-)

The reason I did not include in Guix is because of unclear licensing on
a file.  I emailed the author in Jan. 2015 but didn’t get an answer:

I’m looking at packaging NLOpt for Guix, a free software GNU/Linux
distribution.

I noticed this paragraph in luksan/COPYRIGHT:

    Subroutines PBUN, PNEW, PVAR, PSEN, Copyright ACM, 2001. The original
    versions were published in Transactions on Mathematical Software, 
    Vol.27, 2001, pp.193-213. Here are the author's modifications. They
    are posted here by permission of ACM for your personal use. Not for
    redistribution. Subroutines PLIP, PSEN, Copyright Jan Vlcek, 2007. 
    The remaining subroutines, Copyright Ladislav Luksan, 2007. Many of  
    sparse matrix modules were prepared by Miroslav Tuma.

My understanding is that these subroutines cannot be redistributed nor
modified by anyone; what do you think?

Thank you,
Ludovic.

Could you check if this is still relevant, and possibly get in touch
with them?

Thanks,
