I load quicklisp from my .ccl-init.lisp file, but with 1.8 the loading of quicklisp fails.  My other CL installations still work fine - CCL 1.7, SBCL 1.0.55, and CLISP 2.49.

No it isn't; the version of ASDF distributed with CCL 1.8 doesn't unconditionally
assume that the internal symbol CCL::FASL-VERSION is BOUNDP.

Older versions of ASDF did so, and your init file is apparently causing
one of those older versions to be loaded.

If it were a problem with "the SWANK<->CCL 1.8 interface", it would presumably
have to be a problem that no one else seems to notice.  At first glance, that
doesn't seem like a very plausible explanation.

I'd recommend debugging.  Someone who has an exact copy of your init file and
of the exact versions of the code that your init file loads could do this for
you, but you're probably the only person who meets those requirements.

Typing :b and a newline at the break loop prompt above will show a backtrace, and
the sequence of calls to LOAD in that backtrace would likely show you what's
loading an old version of ASDF.

Setting *LOAD-VERBOSE* to T early in your init file might help you to determine
what's loading an old version of ASDF (though some of the things that're involved
may override that.)

My understanding is that QuickLisp uses its own version of ASDF; if so and if
your QuickLisp installation on that machine is very old you may want to update
it.
