I tried cells on clisp and it didn't work 'out of the box'.
Firstly, the two .asd files are missing clisp in the list of supported platforms.
Secondly, my clisp (compiled with all defaults) choked on the copywrite © symbol, maybe it should be changed to the more traditional (C) for the sake of portability.
I'm using current-cells.zip dated 8th Nov.
