C libraries are easiest to install system wide. The situation with multiple versions of libc is tricky to work with.

Not impossible, just not easy to comprehend by an average dev.

I'm kinda horrified to think there might be people writing C who don't know how to handle library versions. Somehow I don't think that is the target audience here, by I might be wrong.

You might need to install libxml2 in order to use XML parsing library for your high level programming language.

You don't need to be writing C code to be affected by the dependency hell.
