Error building leveldb-sys v2.0.4 in macOS Catalina

[tuler]

Error building leveldb-sys v2.0.4 in MacOS Catalina 10.15.1
I also tried to install leveldb using homebrew. No difference.
Who is to blame here?

error: failed to run custom build command for `leveldb-sys v2.0.4`

Caused by:
  process didn't exit successfully: `/[...]/target/debug/build/leveldb-sys-6dc376d2aa14157c/build-script-build` (exit code: 101)

This should be filed against leveldb-sys. Also, can you rerun the command with RUST_BACKTRACE=1?
