OpenSSL version does not support compression Rebuild with zlib1g-dev package for zlib support
Did you build sslscan with make static, and do yo have the zlib headers installed? If you're building against the system OpenSSL then that's unlikely to support compression.
This is the homebrew version of sslscan, which still does this. Looking at the configuration here: https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/s/sslscan.rb
Homebrew is linking against the brew version of openssl, which is built without zlib support, rather than an embedded version via make static. It's unclear if brew would support their build infrastructure doing an outcall to fetch openssl via git for the embedding.
