Python, Tcl, Tix ...

Checking the Makefile after configure, there are problems with include
paths in TCL_SRC_DIR, TK_SRC_DIR and INCLUDES (which uses TCL_INCLUDES
and TK_INCLUDES).

TCL_INCLUDES and TK_INCLUDES point to the build directories. But we
cannot just put ${prefix}/include/tcl or ${prefix}/include/tk in here.

The real problem is that our Tk installation is missing files which are
for example shipped with the build from Apple. In particular where I
discovered the first build error, Tix looks for tkInt.h which is missing.

Apple ships it at:
/System/Library/Frameworks/Tk.framework/Versions/8.4/Headers/tk-private/tkInt.h

After 'port extract tk', it can be found at:
$(port work tk)/tk8.5.6/generic/tkInt.h

This port needs a similar approach as the tk port itself does. It
extracts the Tcl source and has additional preprocessor flags to search
there for include files:
  configure.cppflags  "-I${workpath}/tcl${version}/generic"

Or we need to copy these private header files to the usual include
location. Maybe it would be good to ask upstream on the Tcl mailing list
for advice on this topic.
