;;; Warning: You are using ASDF version 3.1.8.2 (probably from (require
\"asdf\") or loaded by quicklisp) and have an older version of ASDF 3.1.7
registered at #P\"/usr/share/common-lisp/source/cl-asdf/asdf.asd\". Having an
ASDF installed and registered is the normal way of configuring ASDF to upgrade
itself, and having an old version registered is a configuration error. ASDF will
ignore this configured system rather than downgrade itself. In the future, you
may want to either: (a) upgrade this configured ASDF to a newer version, (b)
install a newer ASDF and register it in front of the former in your
configuration, or (c) uninstall or unregister this and any other old version of
ASDF from your configuration. Note that the older ASDF might be registered
implicitly through configuration inherited from your system installation, in
which case you might have to specify :ignore-inherited-configuration in your in
your ~/.config/common-lisp/source-registry.conf or other source-registry
configuration file, environment variable or lisp parameter. Indeed, a likely
offender is an obsolete version of the cl-asdf debian or ubuntu package, that
you might want to upgrade (if a recent enough version is available) or else
remove altogether (since most implementations ship with a recent asdf); if you
lack the system administration rights to upgrade or remove this package, then
you might indeed want to either install and register a more recent version, or
use :ignore-inherited-configuration to avoid registering the old one. Please
consult ASDF documentation and/or experts.
