Hello,
[I hope it's okay to mail you directly - I mailed cl-irc-devel
initially, but the list apparently requires subscription.]
I tried to install cl-irc 0.8.1 through asdf-install on SBCL today and got
this error:

; compiling (DEFUN READ-MESSAGE-LOOP ...); compilation aborted because of fatal error:

Line 349 of protocol.lisp is in this function:

                 nil)))
       if decoded
       do (return decoded)))

The flexi-streams package that asdf-install automatically installed is
1.0.5. The flexi-streams documentation
(http://weitz.de/flexi-streams/) doesn't refer to any
flexi-stream-encoding-error, though there is an
external-format-encoding-error. Replacing the former with the latter
allowed cl-irc to compile, though I haven't used cl-irc enough at this
point to tell if this is actually correct.
Could someone [you :)] confirm that this is change is correct?
I think this is indeed correct: the flexi-streams version cl-irc used
to be based on was a pre-1.0 version. Apparently, some classes have
been renamed. I'll check in the repository if this has already been
updated. If not, consider it so. However, since there's some partially
completed code in the trunk, I can't really create a new release the
way it is now. So, until usocket has its 0.4 release, we're stuck with
the version currently available on the web as the latest release.
Bye,
Erik.
