I only use a few ruby packages. However, you said it yourself, ruby and
pacman both have different uses, my point was: do not change the content of
a dir managed by pacman, do so elsewhere. I'm not saying you shouldn't ever
use both. In the end, we're free to do anything we want, I just think it is
bad practice to mix things up like described above. In extreme cases, just
have a look at Windows, where anybody can install anything anywhere, we all
know what it ends up like :P
