how to set-up ruby and gems on bamboo ondemand ?

Question

I somehow successfully installed ruby (using rvm) on a custom edited AMI but for some reasons the bamboo agent doesn't recognise the gems ( sass -v throws   not found error, compass does the same).

Any help would be higly appreciated. I can't believe bamboo doesn't support ruby out of the box !

@James: I assume by that you mean that Atlassian OnDemand does not support Ruby and should warn potential users that they should hence stay away from the product or opt to self-host?

If you are not too sold to Atlassian tools (as I am) try to stay away from Bamboo as much as possible! It seems designed only for java. Setting up ruby on bamboo is painful !

For a ruby, python, golang, node etc project I would recommend Travis-CI.

Anyway I finally got it working on bamboo as I had no choice and here is what worked and what didn't work

What did work : 
install ruby through rvm. Make sure you install it as "bamboo" user otherwise it may not work.

provide the executable paths to Bamboo through the Image configuration. E.g. 
/usr/local/bin/node
/usr/local/bin/grunt
/usr/local/rvm/gems/ruby-1.9.3-p448/bin/compass
/usr/local/rvm/gems/ruby-1.9.3-p448/bin/sass
/usr/local/rvm/gems/ruby-1.9.3-p448/bin/scss

sudo chown -R bamboo /usr/local
Look for the gems in  /home/bamboo/.rvm/gems/ruby-1.9.3-p448@global/bin
get root access (sudo su) and then install the gems using the rvm path of the bamboo user :
/home/bamboo/.rvm/bin/gem install sass compass susy

What was supposed to work but didn't work:
rvm 1.9.3. @global do install compass susy sass etc
rvm 1.9.3. @global do gem uninstall rubygems-bundler
rvm use 1.9.3@global --default
Compile ruby 1.9 from source (no rvm)
and more...

I don't see how that would help .
