Comment (by Guymer):

 Whilst I have been able to get `gcc11` to build (by using the patch in
 [ticket:63677]) I have not been able to install `py39-numpy` as I have
 been getting the same error. I uninstalled `gcc11` (and all `+gcc11`
 ports), I installed `gcc-devel` instead and I still get the same error
 (after running `port clean py39-numpy`).

 For info:

 {{{
 sh-3.2# port installed | grep gcc
   fftw-3 @3.3.10_0+gccdevel (active)
   gcc-devel @12-20211127_0 (active)
   gcc_select @0.1_9 (active)
   libgcc-devel @12-20211127_0 (active)
   OpenBLAS @0.3.18_0+gccdevel+lapack+native (active)
 }}}

 For info:

 {{{
 sh-3.2# port select --summary | grep gcc
 gcc         mp-gcc-devel   mp-gcc-devel none
 }}}

 The failed build:

 {{{
 sh-3.2# grep error
 /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports
 .org_macports_release_tarballs_ports_python_py-numpy/py39-numpy/main.log
 ...

 __FLT_EVAL_METHOD__."
 :info:build    68 | #   error "Unsupported value of __FLT_EVAL_METHOD__."
 ...
 }}}

 I find it interesting that when I list the `lib` folder it appears as if
 the `libgcc` files have not been updated.

 Is it possible that `gcc11` did not clean up after itself when it was
 uninstalled? Given that I was able to get `gcc11` to install at the start,
 why didn't `py39-numpy` then install? Surely I should not need to revert
 to `gcc-devel` if I can get `gcc11` to install.
