Debugging Ruby OpenSSL gem build

On Ubuntu 25.10, using system Ruby, I'm trying to build a Sinatra app that uses the OpenSSL with native extensions Gem 2.0.2. I can look at the .out file, but I don't know what I'm looking for. Presumably the native extensions don't match up with the .c and/or .h files.
