SLIME in portage is too old (2.0_p20070816-r1) and needs an update to work with clisp-2.44* From the Changelog in slime's cvs: 2008-02-22 Mark Harig <idirectscm@aim.com> Fixes for CLISP 2.44. * swank-clisp.lisp (sldb-backtrace, %parse-stack-values): sys::frame-up-1 no longer exists; use sys::frame-up instead.
fe[nl]ix, please advise. Can we move a new snapshot from the lisp overlay to the main tree?
app-emacs/slime-2.0_p20080731 should fix this. Please reopen if the problems persist.
