Yes. I'm not up-to-date as to latest Emacs package best practices;
we should ask someone who knows for sure.

Makes sense. Can the path be overridden? How?
For production code, you usually don't want to rely on stuff in ~/

Yes, I filed a bug for that and that was fixed in 15963.

You may want to update your CCL.

That sounds totally probable for ASDF 1 and very early ASDF 2 —
actually, this kind of unstability was one of the reasons that made me
start hacking ASDF. But that sounds quite surprising in ASDF 2.003 or
later (Jun 2010) — unless the problem was failure to recompile things
that depend on modified systems, in which case the problem was only
completely fixed in ASDF 3 (February 2013). If this memory is more
recent than that, this is definitely a bug worth reporting.

PS: To João, Allegro ships with ASDF 2.23.7, but if you run update.sh,
it will upgrade you to a quite recent 3.0.2.3.
