xapit 0.3.x doesnt work with rails 3.2.11

[zabarabab]

I've tried to use xapit 0.3 with rails 3.2.11 (and rack 1.4.5):

Bundler could not find compatible versions for gem "rack":
  In Gemfile:
    xapit (~> 0.3) ruby depends on
      rack (~> 1.2.2) ruby

    rails (= 3.2.11) ruby depends on
      rack (1.4.5)
