gnupg & gnupg2

[Troy Telford]

I'm normally a Gentoo (linux) user, so I'm wondering if MacPorts has similar 
functionality:

In Gentoo, when there are multiple versions of a package (such as gnupg vs 
gnupg2), you can select which one is 'active' using a tool called eselect.

Basically all that happens is some symlinks are moved around (ie. gpg -> 
gpg[12].  Does MacPorts have anything that does this, or do I have to do such 
things manually?
