problems on adding an package to a image using simple-cdd

Hi:

I'm using Lenny but trying to build a etch custom CD. I was successful
until tried to
include sun-j2re1.5_1.5.0+update16_i386.deb created with make-jpkg.
Putting this package in a custom-packages/ directory and adding it to
my profiles/my.packages:

sun-j2re1.5

and doing:

 build-simple-cdd --graphical-installer --profiles my \
	 --keyboard br-abnt2 --locale pt_BR --auto-profiles my \
	 --debian-mirror http://ftp.br.debian.org/debian \
         --local-packages custom-packages --dist etch

it leads to:

<lots of things>
custom-packages/sun-j2re1.5_1.5.0+update16_i386.deb: component guessed as 'main'
Created directory "/home/lucas/simple-cdd/tmp//mirror/pool/main/s/sun-j2re1.5"
Exporting indices...
<more things>
ERROR: missing required packages from profile NAME:  sun-j2re1.5
make: ** [debian-test-image] Erro 1

and bails out.

I don't know if the problem is that sun-j2re1.5 package is 'guessed as
