It looks like CAMBL-TEST has genuine bugs. Maybe the variable
*EUROPEAN-STYLE* is never defined,
maybe it's defined in a file that is not a dependency and ends up
being loaded after rather than before mention,
in either case that's a bug. I wouldn't be surprised that the user
assumed :serial t but didn't specify it,
and that the missing package has the same cause. If you didn't build
from clean, that makes ever more sense.

Yes, this immensely frustrating experience was educating indeed.
Upgrade can never be synchronous.
If a future ASDF developer wants to tighten the compiler static
checking, he will have to provide
either a set of default overrides for known old versions of existing
systems, or a way for quicklisp
to slacken the checks around its packages, or both. In any case, some
out-of-band configuration controls.
