The message is perfectly clear to me :)
Perhaps it would be clearer to other people if it were
more elaborate. For example,
"ratdiff variable x is embedded in the non-rational
subexpression log(x+1), and therefore its specially
efficient method of differentiation cannot be used.
You can use diff(..,x) instead. "
This could be changed without offending the author of ratdiff. (me)

thanks for the info (another reason I should read lisp code).
A short version might be:
" for non-rational expressions, use diff instead of ratdiff " .
