Basically, this behaviour is exactly tht of activate/deactivate. You can
choose which port is active by doing:

port deactivate gnupg; port activate gnupg2

I am not sure if it really works for gnupg2/gnupg as I do not know if
they both install /opt/local/bin/gpg. However, this should be the case,
and it means you have to deactivate gnupg when you "install" gnupg2
(install contains activating).

For finer ways, there was a proposal of a port_alternatives (as in
debian, pkgsrc or probably gentoo) that would allow you if you have
several ports providing gpg or mysql or python... that would
create/update the adequate symlink to the chosen app and prevent
conflicts when you install two ports providing the same file. I am not
sure it is being implemented.
