At that time (around 2012) there were the following options to download http material: perl, wget, curl. I used perl for nostalgic reasons: in the past it used to be the ultra-portable "Larry Wall Meta-Operating System" that worked without further ado on all platforms. This is no longer the case. We also see strange fragmentation into perl packages and sub-packages. Maybe we need a docker container just for one big Perl :-( Anyway, I will take another look at curl. It seems to be universally available on all platforms now, with very similar versions and installation options.
