Compiling Deno from source: Could not run `gn`: Os { code: 2, kind: NotFound, message: "No such file

I'm currently trying to compile Deno from source on raspbian arm32 (since there's no prebuilt binaries for arm32) and I'm running into the following error:

The current directory is /home/z/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/v8-137.2.1
  gn gen --root=/home/z/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/v8-137.2.1 /tmp/cargo-installoYPBs7/release/gn_out

  --- stderr

I have gn installed via apt and I can run it from the commandline, so I'm not sure why I'm getting this error.

I think you might have discovered the reason why we don't provide arm32 builds of rusty_v8, see https://github.com/denoland/rusty_v8/issues/1746#issuecomment-2747454214

any way I can cross-compile from an x64 host?
