Comment (by cjones051073):

 one other comment. The build log is for gcc9, which means libgcc9 must
 have built OK. Both share the same build, so if libgcc9 worked gcc9 has to
 as well, unless you have not cleaned you build before trying. so also do

 {{{
 sudo port clean gcc9 libgcc9
 }}}

 then try again.
