Does he prefer fighting libtool, make, cmake, configure, automake, autoconf and autoreconf just to add a couple libraries into his project? When I tried to use C, I wrote 10 lines of code and spent hours trying to make all that shit work. It makes me laugh when people say Rust is complicated.
Whether you need -dev packages (for headers) depends on your operating system. I run Gentoo. All headers are always on the system. Other distributions ship the headers separately in -dev packages to save space and you need to install them. You likely can install all -dev packages for everything on your system so you do not need to get the individual ones.
