I managed to build from your source directory by doing the following:

* add build-depends gem2deb and rake-compiler

* adding ruby to the dh --with statement in the catch all target (%)

* adding --buildsystem=ruby to the above mentioned dh statement

* using dh_ruby --install in override_dh_auto_install

* patch the Rakefile to use a rake extension to put the ruby extension
  together with the ruby code, something like this:

    +require 'rake/extensiontask'
    +
    +Rake::ExtensionTask.new("ruby-watchman/ext") do |ext|
    +  ext.lib_dir = "lib/ruby-watchman"
    +end

* removing manual copying of the watchman(1) man page and use
  debian/watchman.manpages. (Or ensure that /usr/share/man/man1
  exists.)


I am a bit unsure if it works though, I couldn't require 'ruby-watchman/ext'
from the installed package...

Yes, X(S|B)-Ruby-Versions, in source and binary package stanzas in
debian/control. For more info see

    https://wiki.debian.org/Teams/Ruby/Packaging#Values_of_XS-Ruby-Versions

At the moment I guess ruby2.1 and ruby2.2 are supported, which are
the ones being built for if you supply "all".

PS. I didn't realize that this is not a Ruby package but only includes a
Ruby gem. It doesn't make sense to put in the pkg-ruby-extras repo of
course. :-)
