Does this Nix package build correctly on your Slackware?

I thought I'd better make this as a thread for you to check out in your spare time! the build will take around 5-20 minutes, you might already know that.
Like I mentioned in my blog, I updated Nix to 2.23.1 on my repo, but I'm having issues making it compatible with Slackware 15, it works on -Current though;
I suspect the problem is with the autoconf-archive, libseccomp or.. versions on Slackware 15.

Please let me know if you managed to build this on Slackware 15 ;)
Keep me posted!
