Fwiw, in all my Ghostel updates recently, the Zig module failed to compile, with an error message from Zig about a line in the module source. I have a fairly up to date Zig installed via Homebrew.

I didn't have time to fix it so downloading the binary module has been the only option.

I had the same problem with vterm when I first tried it. The C module failed to compile, with a compiler error about a line in the source. As there was no downloadable binary module I fixed that one.
