 Replying to [comment:21 harens]:
 > Once we've tested whether all these fixes work, I'll write patches for
 the portfile to do all of this automatically. Thanks for your help.

 I ran the following:

 {{{
 36-109:~ svacchanda$ sudo port extract vlang
 Portfile changed since last build; discarding previous state.
 --->  Fetching distfiles for vlang
 --->  Verifying checksums for vlang
 --->  Extracting vlang
 36-109:~ svacchanda$ sudo sed -i "" "10d" "$(port work
 vlang)/v-weekly.2022.13/vlib/sync/sync_darwin.c.v"
 36-109:~ svacchanda$ sudo sed -i "" "252d" "$(port work
 vlang)/v-weekly.2022.13/vlib/v/builder/cc.v"
 36-109:~ svacchanda$ sudo port -v -n -o install vlang -universal
 configure.compiler=macports-gcc-6
 }}}

 And it failed again:

 {{{
 0.000    ms C gcc-mp-6
 gcc-mp-6: error: unrecognized command line option '-no-pie'; did you mean
 '-no-pie'?
 builder error:
 ==================
 C error. This should never happen.

 This is a compiler bug, please report it using `v bug file.v`.
