Deactivate currently active version of a port before building?

[Leo Singer]

Hello,

I am working on updating the htcondor port to version 8.1.0. It turns out that the htcondor build produces a faulty binary if an older version of htcondor is already installed. Is there a way to deactivate any installed version of a port before entering the configure phase? Are there any examples of ports that do that?

Thanks,
