Makes it trivial to remove any build dependencies afterward, and the instructions/script are the same no matter your distro (delete the VM). Also, only one script or set of instructions needed to install the deps to begin with, if a VM's used and it's always the same distro & version. Personally, unless I'm running Gentoo I don't like all that crap hanging around my system packages, and this is simpler than learning the best way to deal with it on whatever distro & package manager one happens to compile on, especially if you don't compile from source very often.
