Cannot install on a machine without Xcode command line tools due to digest-crc

[jviotti]

I'm following the xcode-install instructions to install the tool without a working compiler:

Note: unfortunately, XcodeInstall has a transitive dependency on a gem with native extensions and this is not really fixable at this point in time. If you are installing this on a machine without a working compiler, please use these alternative instructions instead

However the installation eventually fails on digest-crc (https://github.com/postmodern/digest-crc), as it also has a native extension:

What puzzles me is that digest-crc states, in their README, that:

Supports optional C extensions which increases performance by ~40x. If the C extensions cannot be compiled for whatever reason, digest-crc will automatically fallback to the pure-Ruby implementation.

Am I doing something wrong?
