Yes, it is upstream fault. There is a lot of stuff there that is a lot
more complicated then needed.
Actually, the package seems upstream dead: the version in sid today is
the same version in lenny ... and even the homepage in debian/control
(http://moulon.inra.fr/ruby/bdb.html) gives 404 now.
I found out that there's someone else keeping an updated version of this
package on github:
https://github.com/knu/ruby-bdb
This repository even builds against Ruby 1.9 ...
Maybe we should switch upstreams and use this code instead, if you (the
DB specialist ;-)) think it's better.
I tried it here: cloned knu/ruby-bdb, then `dh-make-ruby .`, then
created a simple gemspec, removed the extconr.rb at the root and copied
your debian/ruby-tests.yml over (see attached diff). The extensions
build ok for both 1.8 and 1.9.1, but the tests fail and the package
build fails because of that. On 1.9.1 it even segfaults ...
I noticed that there is a different Berkeley DB interface for Ruby, also
called 'bdb', that is available at rubygems.org:
http://rubygems.org/gems/bdb
https://github.com/ninjudd/bdb

There are some FIXME's in debian/copyright
Are you going forward with this package?
