Thanks for all the CPU cycles ;-) and for the fine report!

These look like genuine upstream bugs or lack of support.

Of course we should patch them appropriately (I assume patches already
exist, for instance in Debian).

But it also calls for a mechanism to specify the platforms supported by
a given package–perhaps a ‘supported-platforms’ field in <package>,
which would default to everything?
