I cannot assist you with your script; all I can do is tell you how  
MacPorts works. And I'm saying that if you have "foo 1.2.1_0"  
installed and active, and you say "sudo port -nf upgrade foo" to get  
1.2.3_0, then you will have 1.2.3_0 installed and active, and 1.2.1_0  
installed and inactive. If you would like to remove 1.2.1_0, you have  
two options. Either you can use -u when you upgrade: "sudo port -nfu  
upgrade foo", or after you upgrade, you can uninstall: "sudo port -f  
uninstall foo @1.2.1_0".
