Comment (by kencu):

 Although I see your pasted bit, I don't think your build error is
 primarily due to the lack of "gawk".

 Something else has gone on here. This build log is not from a clean build,
 for one.

 Ventura does have "awk"
 {{{
 % ls -la /usr/bin/awk
 -rwxr-xr-x  1 root  wheel  351504  2 Dec 03:37 /usr/bin/awk
 }}}

 and the libgcc12 build will use it when it is found, so "gawk" is not
 required:
 {{{
 checking for gawk... no
 checking for mawk... no
 checking for nawk... no
 checking for awk... awk
 }}}

 your error seems to have something to do with a failed build of libiberty:

 please clean your build of libgcc12:
 {{{
 sudo port clean libgcc12
 }}}

 and then try your build again, and see what happens. It is possible some
 other header is interfering with the libgcc12 build --
