Looking for help with kustomize port (Go)

[Aaron Madlon-Kay]

It's common in Go to specify version strings as linker flags. Grep the
ports tree like so to see existing ports that successfully set these
flags. It's not uncommon to use the string 'unknown' for e.g. the git
commit when it is redundant or not readily available.

% grep -R -- "-ldflags '-X" .
./devel/git-sizer/Portfile:build.args              -ldflags '-X
main.BuildVersion=${version}'
./devel/shfmt/Portfile:build.pre_args      -ldflags '-X main.version=${version}'
./security/mkcert/Portfile:build.args          -ldflags '-X
main.Version=${version}'
./www/minio-mc/Portfile:      -ldflags '-X ${goproj}/cmd.Version=${relversion} \
./www/minio/Portfile:      -ldflags '-X ${goproj}/cmd.Version=${relversion} \
Aarons-MBP:macports-ports amake% grep -R -- "-ldflags.*-X" .
./devel/git-sizer/Portfile:build.args              -ldflags '-X
main.BuildVersion=${version}'
./devel/shfmt/Portfile:build.pre_args      -ldflags '-X main.version=${version}'
./security/mkcert/Portfile:build.args          -ldflags '-X

./www/caddy/Portfile:build.args          -ldflags \"-X
${go.package}/${name}/caddymain.gitTag=v${version}\"
./sysutils/go2port/Portfile:build.args          -ldflags "'-X
main.version=${version}'"
./sysutils/go2port/Portfile~:build.args          -ldflags "'-X

I was previously trying to override worksrcpath itself (I remember going through the Docs for the build.* settings, but managed to miss this one apparently). I’ve got some Go-specific ldflags left to fix, but at least it builds and runs now.
