rpa-base works like setup.rb in this regard --- since it installs into
$prefix directly, that is supported easily: the associated "helper"
is installdata which will by default copy the contents of data/ to
File.join(::Config::CONFIG["datadir"], "share"), exactly like setup.rb.

RubyGems doesn't really support per-app data currently but I can think
of the following ways to make it work without resorting to nasty tricks
involving __FILE__:
* provide a Gem-aware (but not gem-dependent!) module in the standard
  Ruby lib., which would provide a functionality similar to rbconfig's 
  CONFIG['datadir'], while inferring (if needed) the correct gemdir to
  use, etc...
* perform some (heavy!) "file access magic" in RubyGems: i.e. have
  RubyGems redefine several (singleton) methods from IO, File, etc to
  perform some transparent mapping of the data files at runtime.

Both approaches seem tricky, though.
