ruby test/unit broken

[Elan Ruusamäe]

seems pld packaging has broken ruby test/unit usability:

$ ruby -r test/unit -e 'print 1'
<internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- minitest/unit (LoadError)
        from <internal:lib/rubygems/custom_require>:29:in `require'
        from /usr/lib64/ruby/1.9/test/unit.rb:3:in `<top (required)>'
        from <internal:lib/rubygems/custom_require>:29:in `require'
        from <internal:lib/rubygems/custom_require>:29:in `require'

makes subversion ruby test impossible:
$ make check-swig-rb
cd /home/users/glen/rpm/BUILD.x86_64-linux/subversion-1.6.16/subversion/bindings/swig/ruby; \
  /usr/bin/ruby -I /home/users/glen/rpm/BUILD.x86_64-linux/subversion-1.6.16/subversion/bindings/swig/ruby \
    /home/users/glen/rpm/BUILD.x86_64-linux/subversion-1.6.16/subversion/bindings/swig/ruby/test/run-test.rb \
    --verbose=normal
<internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- minitest/unit (LoadError)
        from <internal:lib/rubygems/custom_require>:29:in `require'
        from /usr/lib64/ruby/1.9/test/unit.rb:3:in `<top (required)>'
        from <internal:lib/rubygems/custom_require>:29:in `require'
        from <internal:lib/rubygems/custom_require>:29:in `require'
        from /home/users/glen/rpm/BUILD.x86_64-linux/subversion-1.6.16/subversion/bindings/swig/ruby/test/run-test.rb:3:in `<main>'
make: *** [check-swig-rb] Error 1

23:57:39 baggins> glen: `ruby -r test/unit -e 'print 1'` works now with ruby-1.9.2.0-4

seems next point missing:
$ ruby -r test/unit/ui/testrunnermediator -e 'print 1'
<internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- test/unit/ui/testrunnermediator (LoadError)
        from <internal:lib/rubygems/custom_require>:29:in `require'

(is ok on ac with ruby 1.8)
