Hi all,
I have just compiled and installed pd-0.49-0 on my Raspberry Pi 3 B+.
When launching Deken to find and install externals nothing happens (of course I have internet enabled in the Pi).
Can anyone suggest how to troubleshoot this?
Compilations and installation worked smoothly, no issue at all.

Are you sure you are looking for the objects that work on Rpi? Because if you have it set up so it's looking for objects that work on a mac for example, the objects come up in a faded kind of way. I know this because I did the this. I think they have to be arm objects.
