Comment 23 for bug 568401

Not sure if this is the right place, but here's how I did it (this is from memory):

* Install required packages

  sudo apt-get install build-essential
  sudo apt-get build-dep indicator-applet

* Get the source for the indicator-applet (don't use sudo here!):

  apt-get source indicator-applet

  This will extract the source in a directory under your working dir

* Download and apply the patch:

  cd indicator-applet-<version>
  patch -p1 < path/to/patch

  /path/to/patch is the path to the patch in comment #14

* build packages:

  dpkg-buildpackage

  This will produce packages in the dir where you ran apt-get source.
