Ruby Bindings test failures

Kou, et. al.,
I got the following ruby bindings test errors on the 1.5.x branch today:

   1) Error:
test_merge(SvnClientTest):
NoMethodError: undefined method `mergeinfo_get_merged' for
Svn::Client:Module
/home/hwright/dev/svn-1.5.x/subversion/bindings/swig/ruby/svn/client.rb:595:in
`mergeinfo'
/home/hwright/dev/svn-1.5.x/subversion/bindings/swig/ruby/test/test_client.rb:873:in
`test_merge'

   2) Error:
test_merge_peg(SvnClientTest):
NoMethodError: undefined method `mergeinfo_get_merged' for
Svn::Client:Module
/home/hwright/dev/svn-1.5.x/subversion/bindings/swig/ruby/svn/client.rb:595:in
`mergeinfo'
/home/hwright/dev/svn-1.5.x/subversion/bindings/swig/ruby/test/test_client.rb:933:in
`test_merge_peg'

211 tests, 1407 assertions, 0 failures, 2 errors

I think it has to do with the API changes from the recently merged
mergeinfo improvements stuff (merged to the branch in r30349). I don't
think it is enough to hold RC1, but we may want to take care of this
before GA.
