Thanks for the quick reply!

My old computer is already unplugged. I was hoping there was a way to run the 
“port installed” command on the /opt/local in my Time Machine backup, but now I 
see that Time Machine did not backup the /opt directory. I guess I will have to 
reassemble the old computer if I want to get the list of ports that I had 
installed before.

Thanks,
++Eric

I recently got a new computer running Yosemite, and I used the Mac OS X 
migration system to only copy over my home directory from the Time Machine 
backup of my old 10.7 machine. I then installed Xcode and MacPorts base. I read 
the MacPorts page on migration to a new OS, and the first step for reinstalling 
all the ports is "port -qv installed > myports.txt”. Do I need to copy over the 
whole /opt/local directory tree from my old machine to be able to use this 
command to get the list of ports that I had before?

I'd just run it on the old machine and copy the output over, since you'd just 
be removing all the ports afterward anyway in order to rebuild them against the 
new system libraries.
