Problem to build my 1st deb-package

[Markus Hetzmannseder <hetzi@hetzi.at>]

Hi,

I´ll try to make debian Packages for gap4.
(http://www-history.mcs.st-and.ac.uk/gap/) 

But I´ve problems to generate the .debs, the following error 
occoured: 

--------- compile output --------------------------------
mozart:/opt/src/gap4-4.1.fix7# dpkg-buildpackage -us -uc 
dpkg-buildpackage: source package is gap4
dpkg-buildpackage: source version is 4.1.fix7-1
dpkg-buildpackage: source maintainer is Markus Hetzmannseder
<hetzi@hetzi.at>

rm -f debian/tmp/*
dh_clean
 dpkg-source -b gap4-4.1.fix7
dpkg-source: error: per-package paragraph 4 in control info file is
missing Package line
------------------------------------------------------------

I don´t know that this massage realy means to me. I think the control-file
is correct, but maybe I´m wrong, so here ist my contol-file:
