 > {{{py-readline}}} does nothing because it is a stub port that holds the
 real python modules such as {{{py27-readline}}}. This is true for all
 python modules in Macports. So py-* ports should never be installed.

 Yeah, I suspected as much, but the fact that it installed without error
 obfuscated the issue.

 I also tried as many other versions of Python as possible, in some cases
 requiring the expansion of the version lists in py-readline and py-
 setuptools.  In one case (python31), the failure mode is completely
 different but the py-readline fix still works.  All other versions from 26
 through 35 behave identically.  The python25 build is currently broken for
 other reasons, so I couldn't test that.  The python24 port was never
 patched to use libedit in the first place, so it doesn't have the issue.
