---------------------------------------+------------------------------------
 I'm trying to run ipython with the TkAgg backend, and I immediately get an
 error upon startup about its not being able to find the correct tk version
 (and yet that version is indeed installed).

 The key error message is `/opt/local/lib/tk8.5/tk.tcl: version conflict
 for package "Tk": have 8.5.7, need exactly 8.5.11
 version conflict for package "Tk": have 8.5.7, need exactly 8.5.11`. This
 used to work perfectly on this machine with Tcl 8.5.9 & earlier but has
 apparently been broken during recent version upgrades?   Running wish
 appears to work fine (starts up with no error message), but starting
 ipython and trying to access any Tk widgets fails this way:

 This probably means that tk wasn't installed properly.
