Description of issue

I installed the Homebrew version of DAR on Linux, and noticed that it wasn't compiled with XZ/Zstd support and other features. Is there a way you can expand the compilation features of the Homebrew version so that other compression algorithms and features can be used?

This is the output of dar --version on Linux:

It looks like some good lad (@carlocab) already did it for me.
