Lost "port" command

[Bill Christensen]

Hey folks,

I installed a non-MacPorts package on my server the other day - 
WordPress command line interface (wp-cli) which uses the "wp" command.  
It's working properly.

But I just went to do my regular updates using MacPorts, and I've lost 
my "port" command.  I'm getting "command not found".

How do I (a) re-establish the port command and (b) keep the wp command?

Thanks in advance.
