Try to figure out where to get some obscure dependency, with the right version number. Discover that the last depency was hosted on the dev's website that the dev self-hosted when it went belly up 5 years ago. Finally find the lib on some weird site with a TLD you could have sworn wasn't even in latin characters.
We should normalize programs that don't use such exotic and impossible libraries that you have to do anything besides type "make" and "make install" for it to work.
In theory it's a no brainer. In practice not so much.
