So, I have set up my my workstation as a Slackware 15.0 desktop with a -
mostly - pkgsrc-2021Q4 based userland. These are the packages I compiled
for myself, since Joyent's binaries are built on EPEL7 (even though they
use PREFER_PKGSRC=yes, so up to date libs) and lack some vital packages
like libreoffice, vlc and firefox. I've applied very simple fixes to to
get those and few others to build. 

The packages are served over SSL using bozo-httpd. And can be found at
the following link:

<https://retrobsd.ddns.net/pub/packages/All/>

I may accept requests for binaries at vms@, tough, in all due honesty,
I don't even know how much I'm keeping this online.

Enjoy :D
