+For minimum support of MacPorts, you need the Command Line Tools, which can be installed using `xcode-select --install`. If you are installing MacPorts from source, you will also want to run `sudo xcodebuild -license`. Note that some ports will require a full Xcode installation, which is available for free on the Mac App Store.

 Several other settings in macports.conf have changed their defaults over the years. Take a moment to compare each line of your macports.conf with the corresponding line in macports.conf.default in the same directory. Unless you know a reason why a line your settings file should be different from the defaults, adopt the line from the defaults file.

 To reinstall your ports:
 
  1. Save the list of installed ports:
 {{{
-port -qv installed > my_installed_ports.txt
-port list requested | perl -pe 's/ .*//g' | sort -u > my_requested_ports.txt
+port -qv installed > myports.txt

-A script has been written to automate Step 4 above more accurately, though it has some caveats. If it fails, you will just have to do it manually. (But see workaround for conflicting ports below.)
+A script has been written to automate Step 4 above, though it has some caveats. If it fails, you will just have to do it manually. (But see workaround for conflicting ports below.)
 
 To use it, you will first need to run steps 1-3 as described above. Then:
  4. Run these commands to 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 my_installed_ports.txt
+sudo ./restore_ports.tcl myports.txt
 }}}
 
 One known issue is that the script will fail if there are conflicting ports in the list. It's possible to have conflicting ports installed provided at most one of the conflicting set is active. If the script fails for this reason, you can delete one of the conflicting ports from myports.txt and then simply run the script again. You may need to do this multiple times if there are multiple conflicting ports listed.
