[Bardot Jerome]

Package: steam
Followup-For: Bug #772598

hi,

today i try to re-install steam but i have the same error.
I try install with dpkg with the package from debian website, apt and synaptic.
Always the same thing even i try to use the patch.
# synaptic download steam:i386
# mkdir steam_1.0.0.49-1_i386.patch/
# dpkg-deb --extract steam_1.0.0.49-1_i386.deb steam_1.0.0.49-1_i386.patch/
# dpkg-deb --control steam_1.0.0.49-1_i386.deb
steam_1.0.0.49-1_i386.patch/DEBIAN
(patch files)
# nano steam_1.0.0.49-1_i386.patch/DEBIAN/preinst
# nano steam_1.0.0.49-1_i386.patch/DEBIAN/postrm
# dpkg-deb --build steam_1.0.0.49-1_i386.patch/
# dpkg -i steam_1.0.0.49-1_i386.patch.deb

Any ideas, i did something wrong ?
( it's my first re-packaging )
