Comment (by howarth@…):

 Blt is a pretty much a nightmare. The upstream developer no longer works
 on it and basically wants to be left alone. One reason is that the package
 is incorrectly written to use many private data structures and calls in
 tcl/tk (which are simply hard coded into the blt sources from an ancient
 tcl/tk release). The proposed change in
 https://trac.macports.org/ticket/40203 resolves the tk side of this by
 replacing the out of date local declarations of private tk data structures
 and calls with those from the private headers of tcl/tk 8.6.0. Since
 MacPorts doesn't package the tcl/tk private headers, the proposed patch
 bundles these from the tcl/tk 8.6.0 sources for the blt build. Eventually
 someone needs to do the same for the tcl private header usage in blt (as
 it uses a number of data structure fields that are no longer used in tcl
 as of 8.5).
