I need some help...

I have been following these instructions: https://www.redmine.org/account/activate?token=2375a89a6b6f6a04b05bc941e93cb3ea82c15a89

I having an issue with this step: Install dependencies using the Gem bundler¶ This step will look at the dependencies specified in the Gemfile: % cd /var/www/redmine % bundle install

When I run the command, I get this error:

[fit54@u ~]$ cd /var/www/redmine
[fit54@u redmine]$ bundle install
The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x64-mingw32, x86-mswin32. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x64-mingw32 x86-mswin32`.

sudo apt-get install ruby`ruby -e 'puts RUBY_VERSION[/\d+\.\d+/]'`-dev

There is no ruby dev environment which is why native extensions cannot be built. Give the above command a try- it should fix the issue.
