thank you so much :)
i had no idea you could do this and it works perfectly!

First, to prevent Heroku from installing certain gems, use the
BUNDLE_WITHOUT config var to specify groups you want to skip. For
example, I do:
heroku config:add BUNDLE_WITHOUT=development test
Then, in my Gemfile:
source :rubygems
gem 'rails', '3.0.0'
group :development, :test do
gem 'rspec-rails', '2.0.0'
# etc...
end
Now Heroku won't install any of the rspec gems.
Second, try running bundle update after updating a gem in the
Gemfile, and it will recalculate all your dependencies and update your
Gemfile.lock for you. What's even better, though, is to only update
gems you specify - for example, run bundle update rails if you
change the rails version in your Gemfile. That way, Bundler will only
update the things it really needs to, which is safer.

I get this error message every now and then:
You have modified your Gemfile in development but did not check the
resulting snapshot (Gemfile.lock) into version control
Most people suggest removing the .bundle directory and running bundle
install again making sure to add Gemfile.lock to the git repo before
committing and pushing to heroku but that doesn't always resolve the
problem.
The easiest way to fix this is by removing Gemfile.lock and pushing to
heroku without it. Heroku then bundles your gems for you, but informs
you that you will soon be required to include a Gemfile.lock.
I am trying to get my head round this problem.
Can anyone tell my why this happens?
I have on occasions tried wrapping certain gems in my Gemfile within
and 'if statement' to prevent heroku from installing them as I only
want them on my dev box. The error only seems to happen in apps that
I've used this technique. Perhaps this is the source of these
problems?
When will Heroku start requiring you to add a Gemfile.lock and what
are the best ways of preventing this problem?
