Comment (by ryandesign@…):

 Usually the error you've reported, "Undefined symbols
 '_rl_username_completion_function'", is caused by a wrong version of
 readline somewhere, where "somewhere" is usually /usr/local (i.e.
 /usr/local/include and /usr/local/lib). If you've already gotten rid of
 that, another possibility is that you have PATH or DYLD_LIBRARY_PATH or
 DYLD_FALLBACK_LIBRARY_PATH environment variables set, pointing to a
 different location where a wrong version of readline lives. Do you? You
 could use the "env" command to see all the environment variables you have
 set.

 It's hard to know how to help you further without additional information
 from you. I'm hoping that if you provide us the entire output of "sudo
 port -v selfupdate" it will suggest a solution.
