It tries downloading pci.ids from remote servers (see the log for URLs). Maybe these servers were down when you were building or you had some network issues. Check if you can access the URLs from the build machine.

My mistake. It was a bad internet connection. I had to restart the VM for Ubuntu 20.04 for the internet to work.
If nothing else I'm gaining experience compiling sources.

Whew!

That took about an hour to complete! See screenshot.
I couldn't get TinyAros to install Hosted On Linux because I couldn't find install.sh or hosted-install.sh and AROS One x86-64 isn't available.
AROS Vanilla (ABIv11) is installed as Native in VMWare which I did test. I tested gcc in a Wanderer shell. In fact I copied the development directory 3 times to make sure!
So to get a Hosted on Linux version to test I compiled it...
