Thanks for the explanation.

If that's the case, I think it makes the original problem Santi brought up a non-issue. In this sequence:

        make prefix=/home/santi/usr
        make install prefix=/home/santi/usr/stow/git
        cd /home/santi/usr/stow/
        stow -v git

the building phase could have used the same prefix as the install phase uses, and git can find its subprograms in gitexecdir (= ~/usr/stow/git/bin) just fine. It probably is even slightly more efficient since it does not have to go through the symlink stow installs.
