I wouldn't say that rvm is not beginner friendly, but I grant that it has other requirements and compilation can break down due to specific library issues on different systems. To my mind, a better solution, however, would be a compromise: (1) write a script to automate the installation of all the prerequisites (packages and specific library versions) in one step using APT, but then (2) recommend using rvm after that.

Note that this solution also compiles stuff on your machine, and in this case it uses system-wide installation locations. One advantage of rvm is that everything is done as a regular user and sandboxed in $HOME/.rvm. Easy to find and remove, if anything goes wrong or you change your mind later.

(Edited because I misread the command line.)

And if you could elaborate on those "dozens of problems" then we would be most accepting. Broad, overarching statements aren't beginner friendly.
