bundle or install ruby-prof failed on windows - ruby-on-rails

Question

Folks,
I tried hard to install ruby-prof on windows xp and windows 7 through bundler, but not lucky at all,
in the main site of ruby-prof, it says we need to install version '0.7.3' for windows, I tried
gem install ruby-prof -v '0.7.3'
but failed, then I tried
gem install ruby-prof -v '0.7.3' --platform=mswin32
it succeeded, but when I run bundle update again, errors still there.
Gemfile is like this gem "ruby-prof", '0.7.3', errors are as below:
Installing ruby-prof (0.7.3) with native extensions
