make clean error

[Tim Wunder]

Not a big deal, but when I do a 'make clean' after a 'make clean', I get this error:
FLAVOR=gnome guile -c \
 "(set! %load-path (cons \"/usr/share/guile\" %load-path)) \

The first 'make clean' works beautifully. 
Now, why would I run 'make clean' if I'd already run it? Age...
