Based on your suggestion, I tried bumping arachne-pnr from its current
version in Guix from way back in 2016 to latest master from September
2018 (see the attached patch).

The build phase fails, but it seems to be for another reason than its
current failure.  However, I’ve never used arachne-pnr and don’t know
much about it.

I’ve Cc’ed Danny who originally added the package.  Danny, would you be
able to have a look and see if anything can be done to fix arachne-pnr?

The failure seems to be due to a missing txt file:

,----
| make: *** No rule to make target '/usr/local/share/icebox/chipdb-384.txt', 
needed by 'share/arachne-pnr/chipdb-384.bin'.  Stop.

Best,
