Routing for Alhambra II in Icestudio 0.5.0 fails

[garretraziel]

I've just opened soc-demo.ice in icestudio, selected Alhambra II as my FPGA board and clicked on Tools -> Build and build failed with this output:

export APIO_HOME_DIR=/Users/garretraziel/.icestudio/apio; "/Users/garretraziel/.icestudio/venv/bin/apio" build --board alhambra-ii --verbose-arachne -p "/var/folders/38/b1q4f74j6kbfytp94m7rnvdm0000gn/T/icestudio-2748fYeLYJY8CuVG"

The stable version (0.5) is very old. You should use the nigthly-build version, that uses the nextpnr tool (instead of arachne, that is considered obsolete)
