Slightly OT, but the general idea of package management isn't hard.

Put the stuff you should have in a list, then compare what you should
have to what you do have. Go get and install what you don't have, then
make a record that you did it.

Everything needed to get these basics right has been known for 40 years
or more - fellows like Wirth and Dijkstra figured it all out way back when.

Sure, there's always modern stumbling blocks (like why we have subslots)
but that's extra to the essential basics.

So why oh why do the latest generation of wunderkinds (not) always get
it so completely WRONG? 3 runs to fetch all the deps? I suppose wget and
curl don't actually do what I think they do then....

Yes, that's the one

I followed that mostly except for forking the repo and writing a small
shell script - I much prefer proper ebuilds to hacky scripts. Even
though I'm a Linux sysadmin I hate ad-hoc shell scripts with a passion
