The problem is that some older versions have different command line interfaces
accepting different sets of options. --installdirs, for instance, is not
accepted by older versions.

We have two options:

1) use packaged setup.rb only when upstream does not ship one

Advantages:

  * build process should be very similar, if not equal, to upstream's;
  * build can behave differently among different packages due to
    different setup.rb versions.

Disadvantages: 

  * ruby-pkg-tools must cope with different setup.rb versions, and pass
    different command line arguments to each one.

2) always use packaged setup.rb even if upstream provides one.

Advantages:

  * ruby-pkg-tools is kept simpler
  * all packages should build the same way in Debian, at least on the
    setup.rb part of the build.

Disadvantages:

  * build process may be different from upstream's; maintainer must
    check that the Debian build works as expected.

It would be nice if others can expand this advantages/disadvantages, and
even add more choices so we can reach a consensual decision is possible.
