That seems fine. I don't know what every single one of them does, but
all of the main ones are present.

The ones complaining about missing /dev entries are nothing to worry
about - those are plugins just looking for hardware that isn't there.
They can be disabled in files in ~/my-ola, but by default, it will
search for every kind of device.
The one that I don't know the meaning of is the IPV4Address.cpp:89
error. I will ask about that.

According to this page, http support is an optional build option. I
wasn't aware of that, but it would be convenient to enable.

To enable it, it needs libmicrohttpd. It looks like guix has a package
for that - nice!
Thank you,
