diff not working



Hello everyone,

	I compiled and installed clisp 2.32 on my Slackware 9.1 system,
using gcc 3.2.3.  I then built and installed Maxima 5.9.0.  Everything
in these steps went smoothly.

	But diff doesn't work.  Other functions seem fine - integrate,
solve, etc.  It just formats the expression with d/dx:

(C1) diff (cos(x), x);
                                  d
(D1)                              -- (COS(x))
                                  dx
(C2) integrate (cos(x), x);
(D2)                                SIN(x)


No error messages are printed.  Any ideas as to why diff isn't working
as expected?
