Comment (by kencu):

 I personally find that making python ports do your bidding is hard.

 I had trouble getting the compiler_wrapper PortGroup to make this work. I
 suspect the needed linker flags were not available during the testing
 phase for posix_memalign test file.

 In the end, I hacked this workaround into the Portfile
 {{{
     livecheck.type      none

 +    configure.cc         ${configure.cc} -std=c99
 -Wl,-lMacportsLegacySupport

     test.run            yes
 }}}

 and it worked, building with the default gcc-4.2:

 {{{
 $ port -v installed  py310-pycryptodome
 The following ports are currently installed:
   py310-pycryptodome @3.15.0_0 (active) requested_variants=''
 platform='darwin 9' archs='i386' date='2022-10-15T11:37:45-0700'
 }}}

 and it seemed to do OK on the test suite:
 {{{
 ....................................................................................................................................................................................
 ----------------------------------------------------------------------
 Ran 2707 tests in 134.797s

 OK
 }}}

 that at least proves that this port can be built. What the elegant fix
 might be remains to be determined.
