May I suggest that you have a look at the "stow" utility which allows
multiple versions of "locally installed from source" software to be present
on a system and allows for very easy removal.

Latest version of stow at

    <https://github.COM/aspiers/stow>

Under a stow build (using prefix /usr/local) and install
(to install-prefix or DESTDIR /usr/local/stow/{package_name}
you can then see all your locally installed from source
software under /usr/local/stow.

You can activate/deactivate which ones appear in the path with the
stow/unstow method, or even have multiple versions present if they are have
version dependent installation directories and names eg
emacs-23, emacs-24 rather than just emacs.
