 ## Some Remarks
 - Have a look on what I wrote on [`go` and `nodejs`](https://github.com/fg2it/grafana-on-raspberry/tree/master/old-versions/jessie/v2.6.0#go) for building v2.6.0. This still holds.
-- Have a look on what I wrote on [`node-sass`](https://github.com/fg2it/grafana-on-raspberry/tree/master/old-versions/jessie/v3.0-beta5#node-sass) for buiding v3 beta. This is the reason for the choice of a jessie based distro in this build. Alternately, I could probably have follow what I did to build [grafana v3.1.1 on wheezy](https://github.com/fg2it/grafana-on-raspberry/tree/master/old-versions/wheezy/v3.1.1#workaround-for-a-c11-compliant-g) to get the needed c++11 compliant g++.

 - Since the PhantomJS binary used is now a proper v2.1.1, previous [trick](https://github.com/fg2it/grafana-on-raspberry/tree/master/old-versions/jessie/v2.6.0#patch-phantomjs) to patch the binary has no [reason](https://github.com/fg2it/grafana-on-raspberry/tree/master/old-versions/jessie/v2.6.0#phantomjsphantomjs-prebuild-npm-module) to be anymore.
 - Finally, you can read the [reason](https://github.com/fg2it/grafana-on-raspberry/tree/master/old-versions/jessie/v2.6.0#phantomjsphantomjs-prebuild-npm-module) for the manual install of PhantomJS.
