Hi, I am building a Lisp development environment on a fresh installation of Ubuntu and I have plenty of problems. When I choose a restart resulting from a condition, Slime crashes. It happened on several occasions. For example when I do: (asdf:oos 'asdf:load-op :aserve) I get: Attempt to modify the locked package COMMON-LISP, by redefining function STREAM-ELEMENT-TYPE [Condition of type LISP::PACKAGE-LOCKED-ERROR] Whatever I choose Slime crashes and the last thing in the REPL is this: ... -install-dir/site/cl-ppcre-1.3.0/scanner.x86f". ; Loading #P"/var/cache/common-lisp-controller/1000/cmucl/local/home/kamen/.asdf-install-dir/site/cl-ppcre-1.3.0/api.x86f". ; Loading #P"/usr/lib/cmucl/subsystems/gray-streams-library.x86f". ;; swank:close-connection: Error in KERNEL::UNDEFINED-SYMBOL-ERROR-HANDLER: the function STREAM-ELEMENT-TYPE is undefined. I have: cmucl-19d, Emacs 21, Slime 2007-05-24, Ubuntu 7.0. When I do the same operation directly (without Slime) the operation is successful. In addition I get "Protocol version mismatch" when I try to connect to Swank server, although I have restarted Emacs, deleted all fasl files and so on. Any help will be appreciated! -- Kamen
