Required dependency libxml not available (Ruby 2.3.3)?

[putztzu]

On an openSUSE 42.2, but probably not important.
Installed Ruby 2.3.3 from the official Ruby repos (not openSUSE)

Running "bundle install" per instructions threw a series of logged errors, but bottom line is the following

gcc: error: /home/user/.rbenv/versions/2.3.3/lib64/ruby/gems/2.3.0/gems/nokogiri-1.6.8.1/ports/x86_64-pc-linux-gnu/libxslt/1.1.29/lib/libexslt.a: No such file or directory

I then attempted to install libxlst manually with the following

gem install libxslt-ruby

But that resulted in an error requiring libxml2, which appears to be deprecated for this Ruby version

Will this project be updated to support later and current Ruby versions, and/or what is the last known version of Ruby that works?

TIA.
