When I followed the instructions correctly, I had no problems. A couple of observations and a question:

1. In the Wiki, in the 'Build from Source' section, under 'Building the Desktop Simulator', the first line
references 'newrpl-comp.pro' and it should be 'newrpl-ui.pro'.

Fixed. Thanks!

'libc6-dev-i386' solved this. You might add that to the Ubuntu dependencies. It is not needed unless building
firmware.

I added that option to the wiki, the nice thing is it allows you to keep the default folders in the project files.

The usual trick of 'reset button/+ - keys/3 seconds' doesn't work and the Windows Calculator Connectivity Kit doesn't recognize the calculator with the new firmware.
What is the recommended method of updating 39gs firmware with a newer one? Thanks!

The "usual trick" still works, but everything in newRPL is much faster so you need to have some training in ancient japanese martial arts. Once you are capable of trapping a fly with chopsticks you'll be able to do this.
There's a way that never fails:

• put your thumb to cover both the + and - keys, turn the calc around and use a paperclip to reset.
  

Or the samurai style:

• Press On-A-F, then use your left-hand thumb on a shift (press and hold), left index finger on the F, while your right hand has 2 fingers hovering over the + and -, not pressing but ready to spring into action. Press that F key and hold it, and as soon as you release it you have a few milliseconds to press + and - and it will work.
