Comment (by howarth@…):

 Both fink and fedora use a different approach which in fink looks like...
 [[BR]]
         for pkg in tcl tk; do[[BR]]
                 mkdir -p %i/include/tcltk-
 private/${pkg}${MAJORVER}/{generic,unix}[[BR]]
                 cp ${pkg}%v/generic/*.h %i/include/tcltk-
 private/${pkg}${MAJORVER}/generic[[BR]]
                 cp ${pkg}%v/unix/*.h    %i/include/tcltk-
 private/${pkg}${MAJORVER}/unix[[BR]]
 [[BR]]
                 pushd %i/include[[BR]]
                         for hdr in *.h ; do[[BR]]
                                 if [ -f tcltk-
 private/${pkg}${MAJORVER}/generic/${hdr} ]; then[[BR]]
                                         ln -sf ../../../${hdr} tcltk-
 private/${pkg}${MAJORVER}/generic[[BR]]
                                 fi[[BR]]
                         done[[BR]]
                 popd[[BR]]
 [[BR]]
                 perl -pi -e "s,%b/${pkg}%v/unix,%p/lib,; s,%b,%p/include
 /tcltk-private,; s,/${pkg}%v,/${pkg}${MAJORVER},g"
 %i/lib/${pkg}Config.sh[[BR]]
         done[[BR]]


 Note that only the generic headers get symlinked outside of the private
 header subdirectory
