Are you using a recent version of Chicken? 
Both 'unless' and 'let-optionals' work with my version (1.74) both with
psyntax and without. Grepping Chicken sources I also get

./ChangeLog.0-20040412: - `let-optionals' and `define-entry-point' are now avail
able under the hygienic macro system

I haven't tried sniffy, anyway.

If I was you, I would upgrade and check the correcteness of my
installation. Also please send a snippet of the code exhibing the
problem.
