Cheers hashtag - will have a look. I've almost certainly just cloned and built the default branch in the repo rather than checking for alternatives.  And you're right - it does take a while to build!  Thanks for the .deb - will try installing that a little bit later today.

**EDIT - as you predicted I'd downloaded the master branch, not your Tegra one.  Downloaded that now and compiling.  The .deb complained of an error when I tried installing with dpkg -i though that may be because of something I've done or because it should be installed differently as it doesn't have dependencies with it? **
