Doesn't work with bundle --pre

[Christian Höltje]

Using gem install bundler --pre I get this error:

Unfortunately, the gem hanna-nouveau (0.2.4) has an invalid gemspec. As a result, Bundler
cannot install this Gemfile. Please ask the gem author to yank the bad version
to fix this issue. For more information, see http://bit.ly/illformed-requirement.

I'm having the same problem when using bundler 1.1.0, 1.0.22 does work tho.
I did some digging in the gemspec file and found this line, which causes the error.

s.add_dependency(%q<haml>, ["= 3.0.25"])

I think it has something todo with #7.

I get this error too, forcing me to not use hanna-nouveau. :(

See my response to #7. This is how bundler is supposed to work.
