 > *** - EVAL: the function DOUBLE-FLOAT is undefined

Did you recompile pluck.ins?  The name of this function was changed
to "double" solely to make clisp happy.  If the error happens
after recompiling/loading, and initmus.lisp/pluck.ins are
up-to-date (i.e. double, not double-float), perhaps a stack
trace would help.
