Comment (by meitarm+macports@…):

 Replying to [comment:1 larryv@…]:
 > Other than `easy_install`, what executables aren’t being symlinked?
 Well, the problem is bidirectional, which is to say, once I switch from
 Apple's Python to MacPort's, switching *back* to Apple's leaves numerous
 of the MacPorts Python executables symlinked. That is, for instance,
 `/opt/local/bin/pydoc` is still symlinked after `port select --set
 python27-apple`, which I would not expect given the presence of
 `/usr/bin/pydoc` provided by Apple.

 These include:

 * pydoc
 * pythonw
 * python-config

 I had at first thought the same thing was happening with `virtualenv` but
 my Mac doesn't seem to have an Apple-shipped copy of that. *shrug*

 That said, the only executable that *never* gets symlinked appropriately
 I've noticed so far is `easy_install`. The others do get symlinked but
 never get touched again, which is unexpected behavior and also leads to a
 lot of confusing version checking.
