New description:

 The migration to tcl/tk 8.6 breaks the ccpnmr so that it can no longer
 render NMR spectra without crashing.[[BR]]
 Confirmed that reverting tcl/tk to 8.5.13 and rebuilding py27-tkinter
 against this version restores full functionality.[[BR]]
 The rendering under tcl/tk 8.6 fails with...

 {{{
 >>> Spectrum successfully opened
 finished opening spectrum Expt_1 ghnhb_3D
 X Error of failed request:  BadDrawable (invalid Pixmap or Window
 parameter)
   Major opcode of failed request:  70 (X_PolyFillRectangle)
   Resource id in failed request:  0x601811
   Serial number of failed request:  47218
   Current serial number in output stream:  47221
 }}}

 IMHO, the migration to tcl/tk 8.6 was premature and should be reverted
 until tcl/tk 8.6.1 is released.[[BR]]
 It is unclear if the defect lies in tcl/tk or _tkinter of py27-tkinter.

Comment (by ryandesign@…):

 I'm guessing at this point we won't be reverting tcl and tk back to 8.5;
 we'd rather move forward. If you'd like to make a case for that idea
 though the macports-dev mailing list would be a good place.
