NOTE:  I am not subscribed to this list, nor do I intend to. 
I just need help with transitioning to CDBS and Colin Walters suggested that I
redirect my questions towards this list.

I really cannot see what would fail in the following diminutive Makefile:

8X-----
CC = gcc
CFLAGS = -Wall -O9
INSTALL_BIN = /usr/bin/install -D -m 755
INSTALL_DAT = /usr/bin/install -D -m 644

all:
        $(CC) $(CFLAGS) foobar.c -o foobar

clean:
        rm -f *.o foobar

install:
        $(INSTALL_BIN) foobar $(DESTDIR)/usr/lib/cups/backend/foobar
        $(INSTALL_DAT) ChangeLog $(DESTDIR)/usr/share/doc/foobar/ChangeLog
        $(INSTALL_DAT) README $(DESTDIR)/usr/share/doc/foobar/README

uninstall:
        rm $(DESTDIR)/usr/lib/cups/backend/foobar
        rm -r $(DESTDIR)/usr/share/doc/foobar
8X-----

The addition of $(DESTDIR) to the software's crude Makefile was all it took to
make it work with a traditional debian/rules made of dh_* -powered targets, but
it won't do with CDBS, for some reason.

I tried the following short debian/rules with it. Compared to my previous mail
to Colin, it improved the situation, in that the binary is built, but then it
does not get installed in the appropriate subdir:

#!/usr/bin/make -f
include /usr/share/cdbs/1/class/makefile.mk
include /usr/share/cdbs/1/rules/debhelper.mk

Could anybody help me fix this Makefile to make it CDBS-friendly?  Thanks!
