Comment (by jmroot):

 Here is what happens if I use your fallback list with MacPorts 2.5.4 on
 10.6:
 {{{
 % port deps ncurses-bootstrap compiler.fallback="macports-clang-8.0
 macports-clang-6.0 macports-clang-5.0 macports-clang-3.9 macports-
 clang-3.4 gcc-4.2 apple-gcc-4.2 gcc-4.0" cxx_stdlib=libc++
 Full Name: ncurses-bootstrap @6.1_0
 Build Dependencies:   clang-3.9
 }}}

 And here is what happens with the one I suggested in comment:5:
 {{{
 % port deps ncurses-bootstrap compiler.fallback="macports-clang-8.0
 macports-clang-3.7 gcc-4.2 apple-gcc-4.2 macports-clang-3.4"
 cxx_stdlib=libc++
 ncurses-bootstrap @6.1_0 has no dependencies.
 }}}
