Then the ssh2 port needs to have it's package name changed to ssh2-2.0.13.

This is where being able to set a variable (CONFLICTS) would allow you to
specify which software can't have multiple software versions installed.

The port would have to have a naming convention of:
<package name>-<version>[-<patch level>]
This is how NetBSD names their packages. When ever a Port Maintainer
submits an update to a port they either increment the patch level (if the
src version hasn't changed) or remove the patch level for a new src version.
This is all accomplished with the patches that I had submitted to the PR
