Comment (by howarth@…):

 The blt fix doesn't have to be committed for pymol to build. The issue is
 that blt (as used in the APBS Tools plugin of pymol) is broken due to the
 switch to tcl/tk 8.6.0 in MacPorts. The private tk internals forked enough
 to break using blt in this context. You can easily see this by the
 following steps. 1) Install pymol using the pymol-1.6.0.diff changes. 2)
 execute pymol and select the APBS Tools plugin 2.1 menu item from the
 Plugin menu in pymol 3) when the APBS Tools window appears click on the
 "Choose Externally Generated PQR" button. This will crash pymol under the
 current blt. If you install the proposed blt packaging from
 https://trac.macports.org/ticket/40203 and repeat these steps, the file
 chooser will appear instead of pymol crashing.
