MacPorts does not provide a built-in way to do that. If you want to  
do that, you can locate an older version of the portfile by browsing  
the MacPorts Subversion repository on the MacPorts web site, then  
download the portfile and place it on your hard drive overwriting the  
current version of the hard drive. (Use "port file foo" to find out  
where foo's portfile lives.) When you're done playing and want the  
current version back, "sudo port sync".
