Building codium on NetBSD

[ghbpeter]

Hello,
I am trying to build codium on NetBSD 10.0. After unpacking 1.96.2 and running build/build.sh command prompt outputs:

...
+++ ../update_settings.sh
300s/'default': true/'default': false/
sed: -E: No such file or directory
219s/'default': TelemetryConfiguration.ON/'default': TelemetryConfiguration.OFF/
sed: -E: No such file or directory
114s/'default': true/'default': false/
sed: -E: No such file or directory
#

and I can find file vscode/cli/src/bin/code/main.rs

I am C++ developer and I don't know this script world. Is main.rs final file from build ? Or build was aborted due to above errors ?
I don't need to create installation package, sufficient should be running codium from build.
What should I do to continue creating executable binary ... /bin/codium ?
