Reinstall ports

To reinstall your ports:

1. Save the list of installed ports:

   port -qv installed > myports.txt
   

2. (optional) Save the list of requested ports:

   port echo requested | cut -d ' ' -f 1 > requested.txt
   

3. Uninstall all installed ports:

   sudo port -f uninstall installed
   

4. Clean any partially-completed builds:

   sudo port clean all
   

5. Download and execute the restore_ports script. (If you installed MacPorts from source and put its Tcl package somewhere other than /Library/Tcl, then you'll need to use the -t option when you run restore_ports.tcl; see ./restore_ports.tcl -h.)

   curl -O https://svn.macports.org/repository/macports/contrib/restore_ports/restore_ports.tcl
   chmod +x restore_ports.tcl
   sudo ./restore_ports.tcl myports.txt
   

6. (optional) Restore requested status: If you saved the list of requested ports, you can now restore the requested flags for your newly installed ports to their former states.

   sudo port unsetrequested installed
   < requested.txt xargs sudo port setrequested
