Comment (by twilsonco@…):

 xcode-select --install hasn't worked since upgrading to 10.9.2 for me.
 I've installed command line tools from the apple developer site though. I
 assume it has the same effect. I tried installing r118121 with a port file
 downloaded manually and with one obtained with subversion.

 In both cases, I get an error that "Unable to execute port: Could not open
 file:". I also set full permissions to the directory with the port file
 and /opt and all subdirectories have 755 permissions.

 I think I'm doing something stupid...
