 The Ruby symbols aren't available when compiling and results in an error:

 This can be solved by setting the `LIBS` environment variable to
 `RbConfig::CONFIG["LIBRUBYARG"]` as has been done here for our Ruby gem:
 https://github.com/mysociety/xapian-full/pull/11

 I was wondering if a more appropriate change would be to update
 configure.ac to set `RUBY_LIBS` automatically if `null`, something along
 the lines of:
