[DRE-maint] Bug#730690: needs versioned build-dependency on ruby-mocha

[Marc Haber]

Package: gem2deb
Version: 0.5.1
Severity: wishlist

building with ruby-mocha 0.11.3-3 from wheezy causes the following build
failure

=> Unit tests
/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- mocha/setup (LoadError)
        from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'

Command failed with status (1): [/usr/bin/ruby1.9.1 -I"lib:test" -I"/usr/li...]

Building with a backported ruby-mocha 0.14.0-2 from sid works. Please
add an appropriate versioned build dependency to be nice to
backporters.
