Build instructions failing

[ammkrn]

The instructions in the README seem to fail on Mac OS. All of the make invocations in the readme, as well as invocations of cargo install fail with

$ make install-sclc
cargo install --path etc/sclc
error: failed to parse manifest at `/Users/ammkrn/rust/scallop/etc/sclc/Cargo.toml`

Caused by:
  found duplicate binary name sclc, but all binary targets must have a unique name
make: *** [install-sclc] Error 101

Info: rustc 1.68.0-nightly (333ee6c46 2023-01-18) Big Sur 11.7.1 GNU Make 3.81

fwiw, I was able to get scli and sclrepl to build by commenting out etc/sclc and etc/scallopy in Cargo.toml.
